Cnidarians
Cnidarians
Jellyfish, hydras, sea animones, corals and other invertebrate animals with tentacles and hollow body. ---Co0leTs24
Cnidarians include jellyfish, anemones, hydras, and corals. They have a stomach and a tentacled mouth and are radially symmetrical.
Jellyfish, hydras, sea pens, corals, hydrozoans, cubozoans, anthrozoans, anemomes, and possibly some parasites.
No, hydras do not have an exoskeleton. They are simple, soft-bodied organisms belonging to the phylum Cnidaria, which also includes jellyfish and corals. Instead of an exoskeleton, hydras possess a gelatinous body structure supported by a hydrostatic skeleton, which helps them maintain their shape and facilitates movement.
Three examples of cnidarians are jellyfish, corals, and sea anemones.
The four groups of cnidarians are Anthozoa (corals and sea anemones), Scyphozoa (true jellyfish), Cubozoa (box jellyfish), and Hydrozoa (hydras and Portuguese man o' war).
Jellyfish, hydra, corals & sea anemones.
The cnidarian groups are broken down first into two large groups; one contains the jellyfish (Medusozoa), and the other contains the corals and anemones (Anthozoa). Within the Medusozoa, there are four basic groups; Cubozoa(box jellies), Hydrozoa(Hyras), Scyphozoa(regular jellyfish) and Staurozoa(stalked Jellyfish). The orgainization of the Anthozoa is more complex, but basically they are the Hexacorallia and the Octocorallia. The Hexacorallia group consists of sea anemones, hard corals, black corals, 'mushroom corals', and the colonial zooanthids. The octocorralia consists of the 8 tentacled soft corals, and sea pens.
Examples of cnidarians include jellyfish, corals, sea anemones, and hydroids. Cnidarians are characterized by their radial symmetry and specialized stinging cells called cnidocytes that they use to capture prey.
they belong to cnidarians
jellyfish belong to the phylum cnidaria. members of this phylum are called cnidarians (the "c" is silent when pronounced). other members of this phylum are corals, sea anemone, and hydras. they all have the common characterisitic of tentacles with stinging cells (nematocysts).
