WebAnimals in this phylum display two distinct morphological body plans: polyp or medusa. An example of the polyp form is Hydra spp.; perhaps the most well-known medusoid animals are the jellies (jellyfish). Polyp forms are sessile as adults, with a single opening to the digestive system (the mouth) facing up with tentacles surrounding it. WebHydras belong to the phylum Coelenterata (also called Cnidaria), which includes corals, sea anemones, and jellyfish. Coelenterates are primarily marine animals, but hydras are found …

WebSep 22, 2024 · Which phylum do hydras jellyfish corals and sea anemones belong to? Cnidaria phylum What do coral and jellyfish have in common? Jellyfish, corals, and anemones all belong to a group of invertebrates called cnidarians. These simple creatures have very soft sack-shaped bodies, which contain no heart, bones, or even brain. WebThe genome of the sea anemone Nematostella vectensis (Nv) (Cnidaria, Anthozoa) was sequenced recently (Putnam et al., Science 317: 86, 2007). In the current study, 22 proteins of Nv were identified as putative phospholipases A 2 (PLA 2) that showed up to 40–50% sequence identity with secreted or intracellular PLA 2 s including those of humans. … WebThe phylum Cnidaria (pronounced “nih DARE ee uh”) includes soft-bodied stinging animals such as corals, sea anemones, and jellyfish (Fig. 3.23 A). The phylum’s name is derived from the Greek root word cnid - meaning nettle, a stinging plant. Cnidarians are found in many aquatic environments. frank gilley norman police
