How do fish get oxygen?

Answer 1

jellyfish get food by eating small fish or zooplankton. Some jellyfish emit stuff towards their prey, which paralyzes their prey. Then the jellyfish grabs the prey with its tentacles and consumes the prey. They kill their prey by using harpoon shaped needles to inject extremely poisonous venom.

Answer 2

Because jellyfish have very thin bodywalls, almost all of their tissues are exposed to circulating fluid, thereby allowing allowing oxygen to diffuse into their tissues, and carbon dioxide and nitrogenous wastes to diffuse out of their tissues and into the surrounding environment.

Answer 3

Jellies are carnivorous, feeding on plankton, crustaceans, fish eggs, small fish and other jellyfish, ingesting and voiding through the same hole in the middle of the bell. Jellies hunt passively using their tentacles as drift nets.

Answer 4

I think fish get their oxygen from their gills. or water , water has oxygen but im stupid i dont know.

Answer 5

Jellyfishes get oxygen by diffusion through all the surface of their body.

Answer 6

They breathe through their skin. Carbon dioxide comes out of there, too.

Answer 7

Jellyfish do not need a respiratory system since their skin is thin enough that the body is oxygenated by diffusion.
