To capture food, jellies have a net of tentacles that contain poisonous, stinging cells called nematocysts. They use their tentacles like harpoons. When you brush up against them they shoot them out and inject the poison . When the tentacles brush against prey (or,say, a person's leg), thousands of tiny stinging cells explode, launching barbed stingers and poison into the victim.
There are primarily two parts to a jellyfish- the bell and stingers/tentacles.
(I think you know which one stings you)
They insert this little thing called a Cnidocyte inside your skin... or at least that's how I think it works.
Jellyfishes inoculate a liquid mixture which can be made up of neurotoxic or emotoxic poisons (toxines) or allergens.
# Neurotoxines cause death by paralysis of the nervous and respiratory system and/or the circulatory system. # Emotoxines cause death by distruction of blood cells. # Allergens cause death by anaphylactic shock.
Jellies hunt passively using their tentacles as drift nets. Their swimming technique also helps them to capture prey; when their body expands it displace more water which brings more potential prey within the reach of their tentacles.
The tentacles and the oral lobes both are covered with stinging cells. When the stinging cells are touched, they pop open and a tiny dart emerges from each stinging cell injecting poison into its victim.
To defend themselves, jellyfish use small structures in their tentacles which shoot out when touched by anything. Though they do shoot at other jellyfish they do not hurt them. Also in the movie Finding Nemo Marvin doesn't get stung because Clown fish and some other types have a protective coating which doesn't let the shooters shoot.

They kill their prey by using harpoon shaped needles to inject extremely poisonous venom
