(Sketched by a camera.) The gallery of images above are a series of macro photographs of a small juvenile Moon jelly from the genus Aurelia. As I mentioned in the previous post I am revisiting some older sea jelly images and shifting them to black and white because I like how the details and forms are emphasized without the distraction of colour.

The series of images below are possibly young and very small Pelagia noctiluca jellyfish (mauve stingers). You may notice a little amphipod ‘riding’ on one of them! Apparently many amphipods have symbiotic or parasitic relationships with gelatinous animals such as jellyfish. I’m not sure what’s going on here – perhaps public transportation – but if you take a look at this
not very good video I have posted here you’ll get more of an idea.

I’m hoping this image can stand on its own because I’m sort of at a loss to describe the importance of the ocean. But you already know.

Back to the Atlantic, and the tiny jellyfish off the Cape Breton coast. And I do mean tiny. The biggest one pictured here, being just over an inch big. To someone like myself, who lives far inland they do seem rather exotic and fascinating. They way they pulse and flow around in the water and the seemingly endless forms. I spent quite a bit of time observing them, and photographing them, using a macro lens. Scooping them into a white bucket and then returning them to the sea. Some, almost invisible, and no bigger than my smallest fingernail. Elegant creatures of grace.
It’s hard to imagine how such delicate soft-bodied creatures as jellyfish could end up on the fossil record but there are some examples. If, like me, you have an interest in fossils, you may want to check out this blog entry: Eternal Jellies in the World Ocean on Graham Young’s blog, Ancient Shore.

You may have noticed there is a tiny crustacean (possibly an amphipod) hanging out the young Pelagia pictured above. Whatever it is, it had itself firmly attached.

There were thousands of these tiny jellyfish near the shoreline. Tiaropsis, leptomedusan hydrozoanin.

It seems I’ve been away from the ocean for too long. There’s always the Pacific…
See you in a couple of weeks! 🙂
