PPT-CNIDARIA CLASSIFICATION OF PHYLUM CNIDARIA

The phylum C nidaria is represented by approximately 10000 species The phylum is classified into 5 classes Hydrozoa hydroids and siphonophores Anthozoa corals and sea anemone. Bauplan. (pl. . Baupläne. ) The generalized body plan of an archetypal member of a major taxon.. A . body plan, . baupläne. , ground plan, ground pattern. , or . bodyplan. , is "an assemblage of morphological features shared among many members of a phylum-level group". GERM LAYERS. Porifera.

There are 9 Levels of Classification that sort all living things. The phylum groups together all the classes of organisms that have the same body plan. . ). (8,761 known species). General Description: . Simplest animals, multicellular. No organs or body systems. Skeleton composed of spongin (soft) and spicules (hard). Symmetry: . Asymmetrical. Feeding: . 1. Cnidocyte. : Unique and defining feature of this phylum. A combined sensory-effector cell.. Cnidocytes. have a single sensory cilium thus are called as the independent sensory-effector cells.. Each . OVERVIEWS. Arthropoda is a much heterogenous group including a variety of animals with divergent views concerning their phylogeny.. Because of this reason , no definite system of classifying this phylum exists..
