they don't they have venom that stings like electricity
jellyfish
No.
Jellyfish don't have venom, they cant poison you but they sting. Jellyfish are very similar to an electric eel because of there like quality's with stings!
they are around four inches across
electrical to heat
no they have tiny barbs in their tentacles or whatever you call them. When the jellyfish rubs his tentacles against you, the barbs get stuck in your skin.
Sorry, they are just not electric. While jellyfish do sting, this has nothing to do with electricity. Jellyfish have specialized cells on their tentacles called Cnidocytes. These cells have "triggers" that, when activated by prey, discharge a thread that punctures and injects poison into the prey.
if your talking about how the sting you i know that there main organs are away from the electric stuff so they don't kill themselves
The jellyfish live in jellyfish fields.
Yes, the box jellyfish IS a true jellyfish.
There are no electric jellyfish and there are no jellyfish named that. You may be referring to many of the comb jellies that refract light into a brilliant display of moving rainbow colors along their comb rows by the waving of their cilia. In that case, the name of one of the most popular species (because it is prominently displayed at the Monterey Aquarium) is the Mertensia ovum, or 'sea nut' jelly. Unfortunately, even though comb jellies are gelatinous marine invertebrates, they aren't in the same order, class, or even phylum as jellyfish. Most comb jellies, and many hydromedusa (closely related to jellyfish), such as Aequorea victoria and Atolla wyvillei, do exhibit bioluminescence in the dark. But alas, no sea jellies can produce electric shocks.
You can purchase jellyfish at Jellyfish Art. They ship tanks and jellyfish anywhere in the US.
