Cnidocytes are specialized cells found in cnidarians that contain stinging structures called nematocysts. When triggered, nematocysts shoot out barbed threads that inject toxins into prey for food capture. In defense, nematocysts can be used to deter predators by stinging them.
Cnidocytes are specialized cells found in cnidarians (such as jellyfish and sea anemones) that contain stinging organelles called nematocysts. The function of a cnidocyte cell is to capture prey or defend against predators by discharging venom-filled nematocysts in response to touch or chemical stimuli.
Cnidarians (Phylum Cnidaria; stinging animals, including sea anemones) use their stinging cells (properly called cnidocytes, Latin for "stinging chamber") in order to capture prey. The cnidocytes are basically a cellular-sized harpoon. When prey bumps into the cnidocyte, a trigger mechanism is activated and the harpoon rushes out. Some species add poisons for good measure. The tentacles are then able to draw food to the mouth, where it is digested and the waste expelled through the mouth (yes, they use their mouth as an anus).
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.
The animal is a jellyfish. Jellyfish have umbrella-shaped bodies and possess specialized stinging cells called cnidocytes, which they use for prey capture and defense.
Cnidarians are a phylum of invertebrate animals that includes jellyfish, corals, and sea anemones. They are characterized by their radial symmetry and specialized stinging cells called cnidocytes, which they use to capture prey. Cnidarians are found in marine environments around the world.
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.

Jellyfish, corals, and sea anemones are examples of organisms found in oceans that use stinging cells called cnidocytes to capture their prey. These cnidocytes contain specialized structures called nematocysts that inject toxins into their prey.
Cnidocytes are specialized cells found in cnidarians that contain stinging organelles called nematocysts. These cells are important for prey capture, defense against predators, and competition for resources. When triggered, cnidocytes release the nematocysts, which inject toxins into the prey or predator, aiding in immobilization or deterrence.
They are called nematocytes. They are one of at least three types of cnidocytes, the very definition of the phylum. Nematocytes sting, the other two types of cnidocytes either adhere, or gum up their prey, substrate, or that guy that wears a helmet and does super glue commercials.
Cnidarians use specialized cells called cnidocytes to catch food. These cells contain stinging organelles called nematocysts, which can inject toxins into prey upon contact. When triggered, the nematocysts can quickly entangle or immobilize small organisms, allowing the cnidarian to capture and consume them. This adaptation is crucial for their survival and feeding.
Cnidocytes are specialized stinging cells found in the tentacles of cnidarians, such as jellyfish and sea anemones. They contain nematocysts, which are small capsules that deliver toxins to prey or predators when triggered.
Cnidarians have specialized sells that are called cnidocytes. They use these special cells to capture prey. Cnidocytes have a special cavity in them called a cnida. Inside the cnida a coiled up tube is held. These tubes can do many different things depending on what type of cnidocyte it is held in, like release toxins, wrap around a prey item or secrete a sticky glue like substance. A lid called the operculum closes the opening of the cnida. Cnidocytes also have a modified cilium called a cnidocil. The cnidocil is like a trigger - when it is touched it forces open the operculum and releases the coiled tube held within.
Nematocysts are specialized stinging cells found in cnidarians, such as jellyfish, sea anemones, and corals. Their primary function is to capture prey and provide defense against predators. When triggered, nematocysts release a coiled thread that can inject toxins into the target, immobilizing or harming it. This mechanism is essential for the survival and feeding of these marine organisms.

Nematocysts are specialized stinging cells found in the tentacles of cnidarians, such as jellyfish and sea anemones. They are used for defense and prey capture by injecting toxins into their target. When triggered, nematocysts release a coiled thread that can penetrate the skin of the prey or predator.
jellyfish and mosquitoes are two creatures that have nematocust a stinging cell used by animals hunting and stunning their prey
