Markus . . . and the Octopus.

Today something extraordinary happened.

It happened when we placed a memorial for a dear departed friend, Markus Kronwitter.

My primary reason for sharing this is for Markus’ family and friends but, I think others will find something here too.

You see, a Giant Pacific Octopus attended and sat right atop the memorial.

Let me recount using photos.

Memorial made by Stephanie Lacasse.

Markus owned and operated North Island Diving in Port Hardy. He was a dear friend and incredibly important to our dive club, the Top Island Econauts. He died more than 3 years ago and the memorial today was to honour him and maybe offer some comfort to his wife Cecelia and his two daughters, Rosie and Jennifer.

The location was Five Fathom Rock just outside Port Hardy. Part of Markus’ legacy is that he fought for this rocky reef to be recognized as a Rockfish Conservation Area. (More about the significance of that in my eulogy at the end of this blog).

After we shared thoughts about Markus at the surface, down we went to the highest point of the reef. We would wait there till the memorial was carefully descended by Steve Lacasse of Sun Fun Divers using a lift bag and rope.

We wanted to position the memorial there, near a sunken metal beer keg. The keg used to be a mooring float on this site. It was put there by Markus but, by mysterious means, had sunk to the bottom.

As soon as we got to where the memorial was to be placed, I saw a Giant Pacific Octopus, fully out in the open.

You can even see the beer keg right in the background.

After about 5 minutes, he retreated partially into his den, likely because of some annoying underwater photographer with flashing lights.

Note that I do know this was a male Giant Pacific Octopus because the third arm on the right was a “hectocotylus arm”. Only males have the hectocotylus which stores sperm. More on that at this link. (This individual also had an injured arm. It was only about half length but will regrow. Yes, some of the awe that is octopuses, is that they can regenerate limbs.)

But then . . . when Steve arrived with the memorial, the Giant Pacific Octopus darted out of his den, landed right atop the memorial and started flashing white. See the memorial under the octopus in the photos below?

Steve Lacasse with the octopus on the memorial which was still attached to the rope and lift bag.

You can imagine how we marvelled as this unfolded and that some pretty big emotions were felt.

Eventually, the Giant Pacific Octopus moved away. Then, the memorial could be positioned as we had intended, but not before a mature male Wolf Eel also went swimming by.

There’s no photo of that I am afraid. I was a little overwhelmed.

Somewhat dizzied by emotion, we continued with the dive.

Below, I include some photos of what we saw, especially to give Markus’ loved ones a sense of what this site is like.

Tiger Rockfish – longevity can be 116 years WHEN given a chance.

See the male Lingcod under the huge mass of eggs? He’s got a lot to protect!

And then . . . just as we were about to ascend, there he was again – the same Giant Pacific Octopus.

How I wish we could have stayed longer. We had to surface to a far less mysterious world, but with hearts full and so much to tell Cecelia, Jenny and Rosie.

Goodbye Markus.

We’ll be visiting again soon.

My Eulogy for Markus.

It’s my great honour to say a few words before we dive on Five Fathom Rock to position Markus’ memorial.

I of course found it excruciating to try to find the words fitting of Markus, because you have to tap into the emotion to find the words.

It’s been more than 3 years since Markus died. Cecelia, Jenny and Rosie you need the words and, even more, you need this place where your thoughts and feelings can be anchored.

In trying to find the words, I dared remember what it felt like to be around Markus. I don’t think that I know anyone else who was quite like him in knowing the right thing to do, no matter how hard it would be and no matter how many injustices he had suffered.

Markus was about making things better and standing up for what was right. He was a man of truth and science. He appeared unflinching in facing reality. He did not suffer fools. He saw through people with crystalline clarity. He walked his own path – in red “holely soles” and multi-coloured pants – and had the wisdom to stop to have Cecelia join to walk beside him.

He made hard decisions.

He . . . was . . . a . . . fighter.

He fought to be here on northern Vancouver Island.

He fought for his girls.

He fought for our dive club.

He fought for the fishes, now flourishing beneath us.

He fought for his life.
[When diagnosed with cancer, he was told he had 2 years to live. He lived for 14 years post diagnosis].

And he has left an extraordinary legacy.

Part of this, is the legacy of Five Fathom Rock.

Markus fought for this to be a Rockfish Conservation Area so that the fish that live here might get a chance to grow bigger, reproduce more, and to thrive.

And there’s success. It’s so beautiful down there Rosie, Jenny and Cecelia. The fishes are thriving – there are clouds of rockfish and it’s so powerful to think that some, like the Tiger Rockfish, might get a chance to live to be more than 100-years-old.

If there were any place where I could picture Markus, it would be here darting around with yellow fins, fish-like himself. Clearly so at home . . . here.

His efforts for Five Fathom included trying to have a mooring here and his creativity was to use a big metal beer keg. It’s down there now, on the highest part of the reef , close to where there are 2 Wolf-Eels. It’s where we’ll attach the memorial.

And how perfect that this will happen at a time when the Lingcod fathers are protecting the next generation, standing guard, not suffering fools, making very clear when you’re trying to get too close without good intent. Fiercely fighting for the next generation, with an extraordinary sense of place.

He loved it here.

It’s impossible to forget him here.

Not that there is any possibility of forgetting Markus or what he stood for.

His legacy of course includes you Rosie, Jenny and Cecelia. He loved you so much and I can’t even imagine how hard he fought wanting to be here still to protect you, to make sure you would always be okay.

Jennifer and Rosie, you are fighters like your Papa Markus.

Jenny – I also think you have his sense of purpose.

Rosie – I think you have his sense of place.

Cecelia – the love in your eyes makes clear how you carry Markus with you always.

Markus Kronwitter.
It is here on Northern Vancouver Island that he found his wild.
It is with you three, that he found love.

How Do Octopuses Poo?

It’s one of the characteristics that unifies every living thing on the planet – we all need to get rid of waste.

How do octopuses do it? See the video and explanation below.

Why share? Because I solidly believe the world can be a better place through understanding and respecting the commonalities and differences of others AND through marvelling at the natural world.

With great thanks to Krystal Janecki for her video and Neil McDaniel and Jim Cosgrove for their knowledge.

Video above: Giant Pacific Octopus defecating by ©Krystal Janicki November 5 2018, Madrona in Nanoose Bay, British Columbia, Canada. Observations are that in areas where octopuses appear to be eating more bivalves like Swimming Scallops, the poo is whiter / paler in colour. In areas where they appear to be eating more Red Rock Crabs, the poo is various shades of red. (Source: Jim Cosgrove, personal communication).

The detail below on octopus digestion is from “Super Suckers – The Giant Pacific Octopus and Other Cephalopods of the Pacific Coast”
by James A. Cosgrove & Neil McDaniel (Harbour Publishing):

“The first structure for food gathering [in octopuses] is the interbrachial web, the umbrella-like membrane between the arms that the octopus used to enfold food such as crabs, shrimps and sometimes even fishes and birds.The web forms a bag-like container that holds prey close the the mouth . . .

The second structure is the mouth. An octopus has two pair of salivary glads, anterior (front) and posterior (rear). The posterior salivary glans produce a toxin called cephalotoxin. in giant Pacific octopuses this is not known to be deadly to humans, whereas in the blue-ringed octopus of the South Pacific it has killed people. When an octopus captures food in its web, it secretes cephalotoxin into the water, where it is absorbed through the gills of its prey. The neurotoxin affects the nervous system and causes the prey to lose consciousness and stop struggling. The octopus can then use its suckers to aid in dismembering prey such as crab.

The beak, the hardest part of the octopus, is made of the same chitonous material as human fingernails. It is black and looks like the beak of a parrot. The mouth also has a specialized tongue called a radula. The file-like organ is covered with tiny, sharp teeth that are replaced when they wear down, much as sharks regrow teeth. The radular teeth shred the prey’s tissue once the beak has bitten the food into chunks. Working together with the beak and radula are secretions of the anterior (front) salivary gland. The gland produces a mixture of substances called enzymes, which cause the food to break down quickly into a jelly-like substance that can be easily digested. A combination of the enzymes and the radula enables an octopus to remove even the tiniest bit of tissue out of the tip of a crab’s leg.

Giant Pacific Octopus beak. It’s made of keratin.

Once the food is captured, eaten and swallowed, it travels along a short tube called the esophagus (similar to the throat in a human) to a structure called the crop. This is not exactly the same as a bird’s crop, but it does function as a storage place for undigested food.

If the stomach is empty, food passed immediately from the crop to the stomach, which despite distinct differences, functions much like our stomach. In the giant Pacific octopus the digestive enzymes do not come from the wall of the stomach but are produced by the live and introduced into the stomach through ducts. These enzymes cause the food to break down into small molecules that the blood absorbs and transports back to the liver. There they are processed and distributed to the cells of the body. This dual-function liver is different from a human’s whose liver primarily deals with the products of digested food.

Now we find another major difference from vertebrates such as humans and also from squids. Once the food in the octopus stomach is digested, the waste material has to be evacuated. The octopus stomach, however, has only a single tube leading in and out. This means that the waste material must be evacuated through the same tube the food entered before more food can be introduced for digestion. You might call this the “digestion on the instalment plan.” The waste comes out of the stomach into the intestine, which encapsulates it and moves it along till it eventually reaches the end of the intestine located at the entrance to the funnel [aka siphon]. Octopus poop, ejected from the funnel, looks a bit like a slender . . . ribbon . . . .

In giant Pacific octopuses the processing of food, depending on what is being eaten, can take many hours. On average these octopuses make six hunting trips a day, reposing in their den most of the time while they process food.”

Lessons Learned from Octopuses

It’s Canadian Thanksgiving and World Octopus Day (OCTOber 8th = get it?).

There’s so much to be grateful for. The health and freedom that allows me to live this life of depth; the love and support of buddies, family and community; AND the lessons learned, ESPECIALLY from octopuses.

What essential life lessons learned from them?

Do not fear what may look foreign;
Respect alternative intelligences;
If necessary, blend in to escape detection;
When you know what you want, hold on tight;
Trust in your ability to squeeze through tight spaces and come out okay on the other side;
Ink out the negative in your life and jet away, leaving it behind you;
Know your home and keep the garbage outside; and
Be big-hearted (octopuses have three), guard the next generation, and use your beak when needed!

And what’s going on in this photo? All is told about my buddy, this female Giant Pacific Octopus, and the Copper Rockfish (see him/her?) in my blog “Gentle Giants. What to do when you find your dive buddy with a Giant Pacific Octopus on her head“.

And thankful for YOU that you care enough to read this blog and help make my efforts feel so worthwhile. I’ll stay at it till I am an octogenarian (and beyond).

Remarkable Giant Pacific Octopus + Wolf Eel Encounter

Trust me, you are going to love the video below!

It is one of the most remarkable encounters I have witnessed in all my dives.

It’s a fortunate enough thing to be able to watch a large Giant Pacific Octopus when it is hunting. In this encounter, the octopus passes directly over a mature male Wolf Eel in his den. THEN, a Decorator Warbonnet emerges as well.

It was an exciting day in this wonderful marine neighbourhood.

I hope this 3-minute clip allows you to share in the awe and excitement.

For me, this was the NE Pacific Ocean equivalent of seeing a giraffe, elephant and rhino in close proximity.

Video and photos contributed by dive buddies Katie Morgan and Diane Reid while on our trip with God’s Pocket Dive Resort.

Gentle Giants. What to do when you find your dive buddy with a Giant Pacific Octopus on her head.

Please note, I have shared our experience below to reduce the misunderstanding and demonization of octopuses NOT to stimulate diver attempts at interactions. What is described below was an unsolicited gift experienced by those with a very high level of dive experience; knowledge of octopuses (and dive buddy) behaviour; and solid safety protocols.

The Kraken?! Devilfish?!

Scary?! Dangerous?! Alien?

Suggest such things about a Giant Pacific Octopus to any scuba diver respectful of marine life who has had an encounter with one of these gentle giants, and there is going to be a very strong response shattering such mythology.

As it always goes, fear and mythology thrive where there is absence of knowledge.

Any negative encounters between divers and Giant Pacific Octopuses that I am aware of, result from divers manhandling them “insisting” on an encounter, or involve octopuses that are habituated as a result of being fed by humans.

We, as divers, are so fortunate to come across Giant Pacific Octopuses in their world where they are invertebrate royalty. We are able to meet them on their turf, and thereby know how inquisitive and intelligent they are. We know they are mighty, highly adaptable predators.

And, we know too, when we look into their eyes, that observation and assessment is being reciprocated.

That preamble was necessary before sharing what happened today.

This did . . . .

1. Dive buddy Natasha Dickinson during the remarkable Giant Pacific Octopus encounter.
See the Copper Rockfish too? ©2015 Jackie Hildering

I had been taking photographs of Lingcod males guarding their egg masses and noted that my dive buddy Natasha Dickinson was signalling me with her light, indicating that she had found something of particular interest.

I took a few more shots and then swam towards her and found . . . my dive buddy with a Giant Pacific Octopus completely covering her face. Sorry that I missed that shot. I was so in awe of what I saw.

Natasha is an incredibly skilled and experienced diver with a deep respect for marine life. She was clearly not afraid, nor was the octopus.

Natasha had taken the precaution of putting her hand over the regulator in her mouth in case the octopus took an interest in that but otherwise, allowed her to explore.

I would learn later that, while waiting for me she had been watching the Copper Rockfish that you will see in all but one of the photos in this blog. This rockfish stuck very near the octopus. A buddy? That I don’t know but escorting a Giant Pacific Octopus on the hunt is a really good strategy. As the octopus flushes out animals from under rocks with his/her arms, the rockfish can grab the prey that do not end up under the octopus’ mantle.

While observing the rockfish, the Giant Pacific Octopus had slowly advanced toward Natasha and she remained where she was, intrigued at what would happened and having a contingency plan.

When I started to take photos the Giant Pacific Octopus gradually backed away but had taken a particular interest in a clasp at the end of a bungee cord on Natasha’s gear.

You can see how her arm was entwined around the cord and how there was some flashing of white in the skin. You can also see the Copper Rockfish!

I believe this octopus was a female, thanks to feedback I received from self-admitted Cephalopod Geek supreme, Keely Langford of the Vancouver Aquarium. Octopus males have a “hectocotylus arm”. In Giant Pacific Octopuses, it is the third arm on their right. The hectocotylus stores the spermatophores – packets of sex cells, two of which are handed over to a receptive female who stores them until ready to fertilize her eggs.

Having the good fortune to get photos of the right side of this octopus, particularly #5 and #7, allowed me to see that the top of third arm on the right is not differentiated and that therefore, this was a female.

Back to recounting our adventure . . . .

After about a minute or two of gently tugging on the bungee cord, Ms. Giant Pacific Octopus let go.

Natasha swam a bit further off, allowing me a few minutes to marvel and photograph this beauty – the Giant Pacific Octopus AND the Copper Rockfish.

When Natasha circled back, the octopus flashed a bit of white as you can see in the image below. Recognition?

We both found ourselves waving goodbye when we, regretfully, had to return to our terrestrial world.

So what to do when you find a Giant Pacific Octopus on your dive buddy’s head? Observe, marvel, take some photos, share and maybe it can help dispel some of the mythology and vilification about these fabulous marine neighbours.

Giant Pacific Octopus Facts:

Enteroctopus dofleini is the world’s largest octopod species with the maximum records for size being 9.8 m from arm tip to arm tip and 198.2 kg.
Average life expectancy is only 3 to 4 years.
Like other octopuses:
- They have a beak with venom, three hearts, blue blood, and their skin is capable of detecting chemicals (as our nose does).
- While many sources report their having 9 brains, octopuses only really have one donut-shaped brain positioned around their oesophagus and then each of their eight arms has many neurons, this is referenced as “distributed intelligence”. Damir Allen explains at this source; “Think of it like a command centre and 8 independent soldiers. They all act semi-independently, and if separated from the main body they will continue to capture food and try to deliver it to a non-existent mouth.”
- Their ink is not just a distraction for predators but contains the chemical tyrosinase which causes eye irritation and messes up the predators’ senses of smell and taste.
- They are jet propelled and are capable of incredible camouflage where they can not only change the colour of their skin but also its texture to blend in with their surroundings.
- They mate only once. From the Vic High Marine website regarding Giant Pacific Octopuses: “Females die directly after they have finished laying and guarding to their egg however males live a slightly longer time. Octopus reproduction starts when a male uses a specialized tentacle [sic, octopuses have arms not tentacles] to pass two spermatophores (sperm packages) to the female. Once given the sperm the female stores the package until she is ready to fertilize the eggs. Before a female is ready to fertilize the eggs she has to find a suitable den. This search can take the future mother up to one month! Once the perfect place is found the female shuts herself in using rocks. From there she fertilizes each egg and gathers them in bundle of approximately 200. She hangs each group of eggs from the ceiling of the cave. This is a long process because, on average, a female octopus can lay up to 50,000 eggs. The incubation time for octopus eggs are six and a half months. During this time the female stays in the cave, not even leaving to eat, attending to the eggs by constantly blowing oxygenated water on to them. When the baby octopuses hatch they are referred to as paralave. These tiny juveniles swim up to the surface joining other zoo plankton and spending weeks feeding on tiny phytoplankton. Once they have developed enough mass they descend to the benthic zone. As for the mother, she waits until all the eggs have hatched then emerges from the cave and dies shortly afterwards due to the starvation she endured during the months she spent devoted to tending her eggs.“

Octopused! A story in grainy pictures.

I am typing with salt still encrusted to my face and hair. I really should warm up from my dive and wash off the NE Pacific before sharing this with you but this is the kind of story you want to shout from the seamount tops. However, be warned, there is a bit of a dark side to the story too.

Today, while doing a shore dive in Port Hardy with the intention of surveying the health of sea stars*, I had the most wondrous experience I have ever had with not one, but two giant Pacific octopuses.

While photographing a sea star I must have disturbed the first octopus because when I looked down, wondering what had caused a massive disruption of hooded nudibranchs from the kelp, there she/he was in full glory – posturing to show me his/her impressive size, hooded nudibranchs undulating all around.

I even ended up with a hooded nudibranch stuck to my mask, which I gently shook off as I am a poor surrogate for kelp!

After I recovered from the shock of this all and mumbled an apology in the guilt of triggering the chaos, I looked at the octopus for a bit . . . and she/he looked at me. We both settled down, apparent in the case of the octopus in that he/she was no longer posturing and reverted to camouflage colours rather than alarm vibrance.

After some minutes, the assessment appeared to be made by this sentient being that I was not a risk; and that there was no need to hide (nor ink!). As a result, for half an hour I was able to (respectfully) follow along as the octopus hunted.

I was allowed to learn about hunting strategy and see how the colour and texture changed as it moved and how the mantle would flash white as it pounced upon prey.

The only thing that stopped this deeply awe-inspiring experience was that dive buddy, Alex Spicer, found a second octopus in the open!

This much smaller octopus was using giant kelp like a hammock.

The divers among you know what a rare gift it is to find one, let alone two, (unhabituated) octopuses out of their dens, certainly during daytime. The underwater photographers and videographers among you would be twitching all the more, knowing what an incredible opportunity this offers to capture the beauty of these giant wonders.

Here’s the dark side. Thankfully it is a literal dark side. My strobes (flashes) didn’t work properly and it was my own doing. It’s been a crazy week of work and, in the flurry resulting from wanting to fit in a dive, I forgot the cables that hook the strobes to the camera.

Yes, I was given what may be the opportunity of a lifetime but failed to fully capture the beauty of it, leaving you with only the grainy images below. However, I got to fully live the experience and had anything changed in the course of events that led to today’s dive, likely I wouldn’t have been octopused at all.

I hope the images are still enough to illuminate the joy and wonder I felt.

[Be sure you scroll down for the photo of the little guy in the kelp hammock!]

Octo-brrr Octopus!

It was 7.2° C (45° F) in the ocean yesterday. Even in summer, I’ve only experienced a high of about 10° C.

Typical for Northern Vancouver Island at this time of year, it was also windy enough for us to abort going out for a boat dive.

Windy, chilly, drizzly, grey . . . what’s a cold-water scuba diver to do?

Get in the cold, dark green water however you can because you KNOW what kind of beauty and wonder are always to be found below the surface, even where you moor your boat!

And indeed, under the dock, at only 6 m (20′) we found a Giant Pacific Octopus (Enteroctopus dofleini), curled up on a piling, incredibly tolerant of this ecstatic marine educator. Octopuses are SUCH intelligent animals. I felt as much like I was being scrutinized as he/she must have felt as I observed and photographed this awe-inspiring creature.

This individual was “only” about average size (23 to 42 kg). They can weigh more than 73 kg! I promise many more details on this species in future blog items.

There was so much other beauty under the dock but, for this blog posting, I will leave it at sharing the wonder of this Octo-brr octopus.

Bring on Novem-brrr to Fe-brrr-ary! The cold-water diving is so worth it!

I would greatly appreciate it if you would let me know, via blog comments, which image (#1 to 6) you believe is the best. This will determine which image ends up in next year’s WILD Northern Vancouver Island Calendar.

Giant Pacific Octopus – Video

Giant Pacific Octopus subtly changing colour and texture. Video by Erika Grebeldinger.

Remarkable video of a Giant Pacific Octopus juvenile subtly changing texture and colour to better match its surroundings.

When full grown, this species can be over 7 m from arm tip to arm tip and over 73 kg = the biggest species of octopus in the world.

The video was taken by fellow Top Island Econauts Dive Club diver Erika Grebeldinger during one of our dives last month. It is testament to the calibre of her diving and concern for the environment that she was able to “capture” such natural behaviour. It the octopus had been agitated, s/he would have flashed red, postured and/or inked.

Having previously posted this video on Facebook, I love Will Soltau’s observation of how the octopus leaves no footprint and what a different world it would be if we humans were more like octopus in this respect.

Thank you so much for sharing Erika!
