Data for the photoelectric effect of silver are Tunicates are marine animals, either benthic (bottom dwellers) or pelagic (inhabitants of open water), that often form colonies by asexual reproduction. They burrow into the sand in shallow waters where there is a current bringing food they can grab with their tentacles. Tunicates are considered acraniate chordates because tunicates and chordates have the following features in common: a 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. Elaboration of the locomotory apparatus and other developments allowed a diversification of structure and function that produced the amphibians, reptiles, birds, and mammals. Segmentation is important because it allows various sections of the body to become specialized and perform activities better because those body parts are used for a specific purpose. A coelom also is present in some more distantly related phyla, including Annelida, Arthropoda, and Mollusca, but the main organs of the body are arranged differently in these phyla. Adults who exhibit gill slits through their various life stages are aquatic. (A characteristic feature may be present only in the developing embryo and may disappear as the embryo matures into the adult form.) They all have an exoskeleton sometime during their life cycle.

Humans are chordates who exhibit all eight of the defining characteristics of phylum Chordata, although some features do not last through adulthood. Corrections? The chordates are named for the notochord, which is a flexible, rod-shaped structure that is found in the embryonic stage of all chordates and in the adult stage of some chordate species. The lineage of chordates is unclear because early chordates most likely had soft-tissue bodies, which made their remains extremely difficult to preserve through fossilized records. Chordates also possess a dorsal, hollow nerve cord which is different to the notochord.
