Question

How is a fish different from a jellyfish?

Answer 1

Jellyfish are forever but fish ain't.

Plus, jellyfish have those tentacle like things attached to thier body and you might confuse em for octopus for that very reason..

but you should really evade confusing em as an octopus cuz octopus might take it as an insult and the next thing you know will be a Kraken taking your house down.. which is pretty tragic :'(

Answer 2

Answer:

Jellyfish and fish have major anatomical differences.

Explanation: Yes, they both swim, but what is truly the difference? Jellyfish have tentacles, whereas fish have fins. Additionally, jellyfish can STING with their tentacles and fish are pretty much harmless to people and other organisms. Also, a jellyfish's swimming pattern is significantly different than a fish's. Biologically, jellyfish and fish are not grouped in the same kingdom, as fish is named "Animalia Chordata", and jellyfish are named "Animalia Linnaeus". Hope that helps :)
