The Amazing World of Jellyfish

Jellyfish are 97% water or something, so how much are they doing? Just give them another 3% and make them water It’s more useful.

A couple of weeks back, I had the privilege to sneak behind the scenes at the SeaLife London Aquarium to visit their new Ocean Invaders exhibit – both the new tanks on display and the jellyfish quarantine area out back. I had a great time, looking around & it was nice to have a bit of glass between me & the stingers for once! Jellyfish first swam our oceans about 500 million years ago – they really are an incredible reminder that evolution is an amazing thing – with over 350 species of jellyfish out there!
A combination of moon jellies, cassiopeia, Japanese Nettle and Amakusa make for a small but expanding collection. I had no idea it was so tricky to breed and maintain jellies (I mean to be honest, it had never occurred to me that anyone every would…).

Jellyfish have always been my overblown fear in the ocean. I think that watching a Lion’s Mane jelly float around, and watching the aftermath of a lot of stung people on a beach in France when I was 6 is probably largely responsible! Not helped by the fact that they have no brain. How incredible is that?!?! The video below shows a jellyfish stinger in slow motion….amazing!

As always, my need to know more about jellyfish has already spawned a mini-collection:

Any more suggestions are more than welcome!
