Join me in the cold, dark, life-sustaining NE Pacific Ocean to discover the great beauty, mystery and fragility hidden there.

The Case of the Killer Plankton

This week’s case is the result of Stacey Hrushowy bringing a unique jelly-like marine creature to my attention.

Forgive the sensationalist blog title but truly, this animal is like the stuff of science fiction.

It’s a 15 cm pulsing, translucent, rainbow-flashing blob that has a fascinating diet!

I’ve narrated a slideshow with video to share this with you. Please see below.

I would not have been able to identify this species without Dave Wrobel and his site jellieszone.com .

    fantastic. really appreciate the narration jackie. thanks for the explantion regarding the difference between ‘jellies’.
    The last few years I’ve noticed more comb jellies in the water both in JS and furhter down in the Strait of Georgia.
    years ago I was at “Atlantis’ in the Bahamas. forget the water slide through the shark tanks, the most interesting part for me were the jelly tanks. many differnt species (lit with black lights?) it was incredible to observe the crazy light shows
    more please

      Hello Gillian

      So appreciate the nurturing feedback and love that you and Jac are racing to provide comments. Sorry, she won!

      I so know what you mean by the jelly tanks. I saw one at the Maui Ocean Centre and sat mesmerized. They are so surreal.

      Big hugs!

    Hello – I recently discovered one of these creatures (about 7 cm) swimming next to our floating dock in Fort Myers, Florida (February 2011). At first glance I thought it was a jellyfish.

    In the water where I spotted it there were thousands of small jellylike creatures that I can only describe as larvae-like. They looked like straight pins (about 2 cm) with a small blob of “jelly” at one end…maybe about the size of a head of a pin.

    That’s a bit of a vague description but do you have any idea what these could be? Are they comb jelly larvae?

      Hello E.L.

      Sorry that it has taken me a few days to “approve” and respond. It delights me that my posting on a species in the NW Pacific might have helped with an identification in Florida. I wish I was better aware of what jellies you might have there but, with the unique “pelagics” showing up your way i.e. the smack of Portuguese Man of Wars early in Feb, I just don’t know other than that is sounds like a type of hydromedusae to me http://faculty.washington.edu/cemills/Hydromedusae.html. The foiks at the Dauphin Island Sea Lab would likely know right away. See http://dockwatch.disl.org/
      Would love to know if you figure it out.
      Very best wishes!
