PHYLUM CTENOPHORA. Biradially symmetrical radiata with gelatinous ectomesoderm containing mesenchymal muscle fibres, with eight meridional rows of ciliary plates present throughout life, or as in four genera, in the larvae only; and with two tentacles (with the exception of one genus) and a biradially structured.
Like Cnidarans, they have a gelatinous body with a similar medusa body plan. • In fact, they were once grouped with the jelly fish in Phylum Coelenterata. • However, they have a few major differences Page 3. Characteristics. ? The body of a comb jelly is divided into 8 equal sections. ? Each section is separated by.
Movement of cilia into one direction help animals to swim other direction – weak swimmers- move passively with ocean currents. • Bi-radial symmetry along oral aboral axis: Tentacular plane &. Pharyngeal plane. Page 7. • Mouth leads to pharynx, stomach and series of gastrovascular canals (similar to Cnidarians).
Ctenophora (/t??n?f?r?/; singular ctenophore, /?t?n?f??r/ or /?ti?n?f??r/; from the Greek ????? kteis 'comb' and ???? phero 'carry'; commonly known as comb jellies) is a phylum of invertebrate animals that live in marine waters worldwide. They are notable for the groups of cilia they use for swimming (commonly
Digestion. Feed on zooplankton, Cnidarian jellies and other Ctenophores. Gut extends through the entire animal, linear digestive tract. Anal pore is at the aboral surface. C?right-Th?
