Ctenophora (/ t ə ˈ n ɒ f ər ə / tə-NOF-ər-ə; sg.: ctenophore / ˈ t ɛ n ə f ɔːr, ˈ t iː n ə-/ TEN-ə-for, TEE-nə-; from Ancient Greek κτείς (kteis) 'comb', and φέρω (pherō) 'to carry') comprise a phylum of marine invertebrates, commonly known as comb jellies, that inhabit sea waters worldwide.
Ctenophore, any of the numerous marine invertebrates constituting the phylum Ctenophora. The phylum derives its name (from the Greek ctene, or “comb,” and phora, or “bearer”) from the series of vertical ciliary combs over the surface of the animal. The body form resembles that of the cnidarian.
Oct 9, 2017 · Ctenophora, comprising approximately 200 described species, is an important lineage for understanding metazoan evolution and is of great ecological and economic importance.
Phylum Ctenophora, commonly known as comb jellies, includes 7 orders, with over 200 currently known species of biradially symmetrical, acoelomate organisms that resemble cnidarians. Ctenophore species are largely planktonic, exclusively marine animals, found throughout the world’s oceans, and comprise a significant portion of the planktonic ...
Oct 15, 2019 · The comb jelly is a marine invertebrate that swims by beating rows of cilia that resemble combs. Some species have rounded bodies and tentacles like jellyfish, but comb jellies and jellyfish belong to two separate phyla. Jellyfish are cnidarians, while comb jellies belong to the phylum ctenophora. The name ctenophora comes from Greek words that ...
Introduction to Ctenophora. Ctenophores (Greek for "comb-bearers") have eight "comb rows" of fused cilia arranged along the sides of the animal, clearly visible along the red lines in these pictures. These cilia beat synchronously and propel ctenophores through the water.
Ctenophores or comb jellies represent the first diverging lineage of extant animals – sister to all other Metazoa. As a result, they occupy a unique place in the biological sciences.
