Tim is swabbing a jellyfish before it dies; jellyfish don't live long in captivity because they're simple sensory tactics can't see glass or the small bits of food we give them.
Hi, I'm Dr. Monty. I'm helping Tim and Schuyler.
Jellyfish have a ring of neurons around their bell; the main part of their body.
Jellyfish usually don't live very long, but the oldest jellyfish ever recorded was estimated to be 1,550 years old. Fun fact, there is a type of jellyfish that is immortal unless it is eaten, in fact it ages backwards.

Jellyfish live all around the world, from tropics to the arctic and from deep waters to shallow.
The medusa jellyfish is able to shrink in size when food is scarce and grow bigger when food is abundant. That is one reason it survives.
