Jellyfish, like their relatives, the sea anemones,
are all carnivores. Depending on the species and
its size, they can feed on anything from tiny
zooplankton to small fish. The stinging cells,
that when discharged are involved in prey capture,
are produced by the jellyfish animal itself by
specific cells called nematocytes. When thinking
about the anatomy of a jellyfish, think of it as
an upside down anemone that is not attached. The
mouth, would therefor be located on the underside,
centered among the ring of tentacles.
It depends on the species of jellyfish.Some eat
small zooplankton, others eat fish.

harpoon that shoots out and injects a small amount
of venom into the prey. Jellyfish are closely
related to sea anemones, which also sting the same

They sting their prey and then bring them

stomach. Inside the cavity they secrete juices
and the food slowly is digested. Like the scene
from Star Wars: Return of the Jedi.
