Ctenophora Definition Ctenophores are free-swimming, transparent, jelly-like, soft-bodied, marine animals having biradial symmetry, comb-like ciliary plates for locomotion, the lasso cells but nematocytes are wanting. They are also known as sea walnuts or comb jellies. Comb jellies are part of a small phylum allied to the cnidarians and similar to them in many ways. They are radially symmetrical like a cnidarian medusa, the body is mostly water, and they capture their prey in a somewhat similar manner with tentacles. But there are many differences. Comb jellies paddle through the sea with iridescent cilia and snare prey with sticky tentacles. They are much more complex than sponges — they have nerves, muscles, tissue layers and light 2010-11-08 · Ctenophores, or comb jellies, are the common names for animals in the Phylum Ctenophora.

Some true organs are present. About 80 species, ranging in size from millimeters to over a meter, are known. The comb jelly is a beautiful, oval-shaped animal with eight rows of tiny comblike plates that it beats to move itself through the water. As it swims, the comb rows break up (diffract) light to produce a shimmering rainbow effect. THE CTENOPHORE NAME All comb jellies, members of Phylum Ctenophora, feature strips called comb rows evenly spaced around their bodies. Each comb row bears a band of tiny, hair-like cilia – the comb-like structures in comb jellies.
These organisms can be found all over the world, sometimes acting as invasive species in areas where they are not native, and causing environmental problems or difficulties in the fishing industry. The phylum Ctenophora is a small phylum containing about 90 species of generally small and delicate animals, known as Comb Jellies or Comb Jellyfish. Many species are almost transparent and a few species can be very beautiful, as they have the ability to produce green and blue coloured light. 2019-10-15 · Jellyfish are cnidarians, while comb jellies belong to the phylum ctenophora. The name ctenophora comes from Greek words that mean "comb carrying." Approximately 150 comb jelly species have been named and described to date. Comb jellies are named for their unique feature: plates of giant fused cilia, known as combs, which run in eight rows up and down their bodies.
They are found in oceans worldwide, although up to 75% live in tropical water. Ctenophores show many similarities to Jellyfish (Cnidaria), but they actually sit in an entirely separate phylum. The phylum Ctenophora, the comb jellies, is a phylum of marine invertebrates. They are part of the plankton, and there are also pelagic species.
