Animals that contain stinging cells, known as cnidocytes, primarily belong to the phylum Cnidaria. This includes jellyfish, sea anemones, corals, and hydras. These specialized cells contain structures called nematocysts, which can deliver toxins to capture prey or defend against predators. The stinging mechanism is a key adaptation for survival in their aquatic environments.

What is stinging cells on a tentacle?
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.
What animals catch food and protect themselves with their stinging cells?
Insects.
What part of the hydra contains the stinging cells?
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.
How long does it take for a stinging cells animal to replace its cells once it is used and discarded?
The process of replacing stinging cells in animals, such as jellyfish or sea anemones, can vary depending on the species and the individual animal's health. In general, it can take a few days to several weeks for these animals to replenish their stinging cells after they have been used and discarded. However, some species have continuous regeneration, allowing them to replace their stinging cells more rapidly.
Where Are the Stinging Cells of a Jellyfish Located?
The stinging cells in a jellyfish are located in it's tentacles.
Why might stinging tentacles be advantageous for slow moving predators such as some cnidarians?
All Cnidarians have tentacles with stinging cells in their tips which are used to capture and subdue prey. In fact, the phylum name "Cnidarian" literally means "stinging creature." The stinging cells are called cnidocytes and contain a structure called a nematocyst.
What is the difference between tentacles and stinging cells?
Stinging cells are cells that "sting" and pour toxins into the bloodstream, and tentacles are long appendages that have no relation whatsoever to stinging cells.
How does coral catch the microscopic animals to eat?
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.
Stinging cells are in what phylum?
Usually stinging cells belong to the phylum Cnidaria
What would contain prokaryotic cells Bacteria Fungi Plants Animals?
prokaryotic cells does not have nuclear membrane surrounded DNA, a characteristic of only bacterial cells.
Do cnidarian have stinging cells?
Yes, cnidarians are animals that are jelly fish like (including jelly fish). Cnidarians have stinging cells located on there tentacle's, they explode once any thing touches it shocking (or paralyzing) any prey that passes by it.
How do stinging cells help a hydra captue food?
Stinging cells in a hydra, known as cnidocytes, contain harpoon-like structures that can inject venom into prey. When prey brushes against these cells, the stinging mechanism is triggered, paralyzing or killing the prey. This allows the hydra to easily capture and consume its food.
