About this document
Characteristics of Phylum Ctenophora by Hafizah Zakiah is a document available to read on EtoBox.
Ctenophores are a phylum of exclusively marine organisms that exhibit biradial symmetry. They use comb-like plates lined with cilia to swim and feed on plankton. Their bodies can vary in form and they may or may not have two tentacles. They have two germ layers and tissue-level organization, but lack a body cavity. Their body wall consists of an outer epidermis, inner gastrodermis, and a mesogloea containing cells that distinguish them from cnidarians.
