Tunicate larvae either seek out a place where they can attach and metamorphose into an adult or develop into adults that float in the open water. All chordates have pharyngeal gill slits at some point in their development. All chordates share the following common features that are unique to the group: The notochord is a stiff but flexible rod of cells and connective tissue (from the Greek root words noto meaning back and chord meaning string) that gives the phylum its name, Chordata.In some chordates the notochord is a major support structure (Fig. Family groups and societal relationships, in both a broad and narrow sense, are particularly well developed in vertebrates, due primarily to their elaborate nervous systems.

All animals eat other organisms in order to gain building materials for the body. What is a Mammal? Because of the unique diversity of this phylum, the habitats that the organisms inhabit are immensely varied and can range from ocean habitats to desert habitats. The chordates are named for the notochord, which is a flexible, rod-shaped . Shown above are four of the major characteristics: the pituitary gland (thyroid), dorsal nerve cord, pharyngeal slits (gill slits), and notochord. Pharyngeal slits are openings in the pharynx that develop into gill arches in bony fish and into the jaw and inner ear in terrestrial animals. Urochordata, which means "tail chordates," also called tunicates, is a subphylum of Chordates. the notochord extends into the head region.

(A characteristic feature may be present only in the developing embryo and may disappear as the embryo matures into the adult form.) spores can germinate only in the right environmental conditions (moist, where there is food), so producing many spores increases the chances that at least one will end up in an area of those conditions.
