The phylum Chordata again consists of two marine groups, i.e., Cephalocordata (includes the fish-like lancelets), Tunicata (for example, the sea squirts, salps and relatives) and Vertebrates (fishes, amphibians, reptiles, birds, and mammals).

The body of the sponge is a loose collection of about six different types of specialized cells. Finally, if the animals that have true tissues and bilateral symmetry also develop an anus first and mouth second during embryonic cell division, then they fit nicely into the category called deuterostome, which literally means 'second mouth.'. It is also significant because, unlike protostomes, deuterostomes have regulative development. Determining Protostome or deuterostome for phyla?

Indeterminate or Regulative Cleavage: This indicates that the fate of the embryonic cells are not predetermined and can be altered during the early stage of embryogenesis if the cells are moved out to a different location. Protostomia and Deuterostomia are considered super-phyletic taxa, each containing a variety of animal phyla. Both protostome and deuterostome are coelomates and possess a true coelom. The coelom (a fluid-filled body cavity lined with mesoderm) develops from buds off the embryonic gut. What are the four characteristics of Protostome development? Protostomes undergo spiral cleavage, meaning that the cells of one pole of the embryo are rotated, and thus misaligned, with respect to the cells of the opposite pole. One unique trait that most echinoderms possess is the ability to regenerate lost appendages.
