jellyfish and mosquitoes are two creatures that have nematocust a stinging cell used by animals hunting and stunning their prey
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.
Nematocysts are the miniscule capsules that a jellyfish's tentacles contain. They are the tiny needles that jellies use to capture and paralyze 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.
