Cnidocytes
Stinging cells on a tentacle are specialized cells called cnidocytes that contain nematocysts. When triggered by contact with prey or a predator, these cells release harpoon-like structures that inject venom, helping the tentacle to defend itself or capture prey.
Jellyfish sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes.
Stinging cells are called cnidocytes, as in all members of the Cnidarians which includes jellyfish, sea anemones, and corals.
The stinging cells in a hydra are located in the tentacles, which are cylindrical, tube-like structures surrounding the mouth of the organism. These stinging cells, called cnidocytes, contain nematocysts that can inject toxins into prey or threats.
The stinging cells in the hydra is what helps it paralyze its prey. Once it uses its stinging cells to paralyze it, the hydra then uses its tentacles to push into itsslef considering that its only one cell layer thin.
The stinging cells of the Hydra paralyze the daphnia.
nemotocysts are the stinging structures an a Hydra
Surrounding a corals mouth are a ring of tentacles, and each tentacle is loaded with tiny stinging cells that contain a miniature barbed harpoon called a nematocyst. When a food item touches an outstretched tentacles, the stinging cells fire harpoons into the animal, which make it stick to the tentacle. The tentacle then pulls the prey into the mouth, and it is then digested.
there is no function. asians use them for their tentacle porn though.
Yes. After discharge, the stinging sac (nematocyst) is often pulled out of its cell (nematocyte). The cell (with or without the stinging sac) is then absorbed by the jellyfish. New stinging cells (nematoblasts) are continually being formed from stem cells, normally at a birthing site near the base of the tentacle. As these new cells form new stinging sacs, they travel down the tentacle and eventually take their place in the outer tissue of the tentacle in a precise pattern, which is often specific to their species.
