jellyfish and mosquitoes are two creatures that have nematocust a stinging cell used by animals hunting and stunning their prey
Nematocysts are the stinging cells of cnidarians (jellyfish, corals, and sea anemones).
roundworms; threadworms; eelworms
Cnidarians
Nematocysts are the miniscule capsules that a jellyfish's tentacles contain. They are the tiny needles that jellies use to capture and paralyze prey.
Cnidarians are unique because they contain cnidocytes when no other organism does. Cnidocytes are cells inside the epidermis of the tentacles and these cells contain organelles called cnidea. There are different types of cnidea in cnidarians such as nematocysts which contain a stinging venom to paralyze prey and spirocysts which contain sticky threads to capture prey.
prey also called carnivores. if the animal also eats plants, it's called an omnivore.----------------------------------------------------------------------------------------just leave it at 'prey' that is the simplest answerpredetors
When an animal kills another animal, the animal that kills that animal is called the predator, while the eaten is called the prey. Let's use a bird and a worm for example, the bird is the predator because it eats the worm, and the worm is the prey because it gets eaten.
A prey animal is hunted and eaten. An example is a lion (carnivore) eating a Zebra (herbivore).
As to the functions: stinging nematocysts function primarily for the capture of prey, and secondarily as a defense mechanism. There are many types of nematocysts, such as those that function to inject toxins to immobilize prey, and those which serve to entangle and hold onto the intended meal by wrapping around it. Species of cnidarian jellies vary in the types of nematocysts they possess, and this can be used to some extent in classifying and identification.
Nematocysts are the stinging cells on tentacles of a cnidarian, like a jellyfish. Since jellyfish don't have any teeth, and their body consists of gelatin, it's hard to capture prey. Nematocysts help jellyfish with feeding by stinging the prey in an attempt at trying to immobilizing the prey.

Though the toxins in their nematocysts are effective against their prey, V. velella is harmless to humans, either because its nematocysts are unable to pierce the skin, or perhaps because humans do not react to the toxins encapsulated in their nematocysts. Nevertheless, it is wise to avoid touching one's face or eyes after handling V. velella. Taken from wikipedia.
All Cnidarians have nematocysts as a specialized organelle. Cnidarians use their nematocysts to capture prey and as a defense mechanism against predators.
Um ... horses eat grass. They don't capture prey. Maybe you are thinking of another animal.
Nematocysts.
They capture their pray by stinging them with their tentacles and then they pull the stunned prey into their mouth, which is in the center of the top of the animal.
Its tentacles contain cells called cnidocytes (if I'm not wrong) that contain toxins to defend itself and capture prey.
A cheetah might learn how to prey and capture an animal
yes
Comb jellies are somewhat different from true jellies (cnidarians). They lack stinging nematocysts and have developed other strategies to feed and protect themselves. Some of these include oral lobes to capture prey and sticky tentacles.
