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.
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.
To defend themselves against predators.
they toss them of with their horns
A porcupine has quills to defend themselves against harm's way (defend them from predators).
Running awayClimbing treesBiting
nuclear weapons
dolphins defend themselve by using their mouths againts predators like sharks and orcas
Giraffes defend themselves against predators by kicking them swiftly while running and a well places kick can kill the predator
They fly up into a tree!
Sloths spend nearly all of their life in the tree tops, where they hide from predators. Some of their predators, like jaguar and ocelots, don't hunt in the treetops. The sloth can't effectively defend itself against predators, and some, such as Harpes Eagles, do hunt in the canopy.
They run away from predators or may defend themselves using their horns.
with venom and camouflage
They'll coil up into a defensive position and rattle their tail and will often strike out with their fangs .
