What animals have stinging tentacles?
Jellyfish, sea anemones, corals and their relatives in the phylum Cnidaria capture food with special stinging cells called cnidocytes, which line their tentacles.
What is the name of the stinging cells that this animal has on its tentacles?
Nearly all (about 99 percent) cnidarians are marine species. Cnidarians have specialized cells known as cnidocytes (“stinging cells”) containing organelles called nematocysts. These cells are concentrated around the mouth and tentacles of the animal and can immobilize prey with toxins.
What type of animal is Hydra?
Hydras are one of the 9,000 species belonging to the phylum 'Cnidaria' which are simple, radially symmetrical invertebrates with tentacles. Other species include coral, jelly fish and sea anemones.
Is Hydra a real animal?
Hydra, genus of invertebrate freshwater animals of the class Hydrozoa (phylum Cnidaria). The body of such an organism consists of a thin, usually translucent tube that measures up to about 30 millimetres (1.2 inches) long but is capable of great contraction.
What animals have nematocysts?
nematocyst, minute, elongated, or spherical capsule produced exclusively by members of the phylum Cnidaria (e.g., jellyfish, corals, sea anemones).
What is polyp and medusa?
There are two basic cnidarian body shapes: a polyp form, which is attached to a surface; and an upside-down free-floating form called a medusa. Some cnidarians change form at different phases of their life cycle, while others remain in one form for their entire life.
Is Jelly a medusa or polyp?
Jellyfish have a stalked (polyp) phase, when they are attached to coastal reefs, and a jellyfish (medusa) phase, when they float among the plankton. The medusa is the reproductive stage; their eggs are fertilised internally and develop into free-swimming planula larvae.
What are stinging cell animals?
Cnidocytes, also known as stinging cells, are specialized neural cells that typify the phylum Cnidaria (sea anemones, corals, hydroids, and jellyfish) [1,2,3]. These cells contain an organelle called cnida or cnidocyst, which is the product of extensive Golgi secretions.
What is a jellyfish sting made of?
Jellyfish tentacles contain microscopic barbed stingers. Each stinger has a tiny bulb that holds venom and a coiled, sharp-tipped tube. The jellyfish uses the venom to protect itself and kill prey. When you brush against a tentacle, tiny triggers on its surface release the stingers.
Does hydra have tentacles?
Hydra are small polyps from 1 to 20 mm in body length. The body is crowned by up to 10 or 12 tentacles. Usually the tentacles are approximately the same length as the body but may be somewhat shorter, particularly in the green hydra, and can exceed 20 cm in length in hungry brown hydra in quiet water.
Is Hail Hydra real?
