How do jellyfish defend themselves against predators?
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.
Jellyfish defend themselves by using their stinging cells to shock the other animals.The primary defense of jellyfish are their stinging cells. Some species have more specific secondary defenses, such as mucus coating to stymie parasitic crustaceans, or luminescence to startle deepsea predators, or camouflage to hide themselves.
they cry. or they dance. or they suicide. ______________________________________ Cheetahs don't have to defend themselves against predators; they ARE the predators. On the off-chance that they needed defense, their speed would quickly carry them away from any threat. However, cheetahs are vulnerable; they are magnificent sprinters, but cannot go any distance. After 400 yards or so, a cheetah is exhausted and unable to run further.
