Sorberaceans: Sorberacea

No Common Name (oligotrema Sandersi): Species Account

Physical characteristics: Oligotrema sandersi sorberaceans are no longer than 0.2 inches (5 millimeters). The oval body is covered by sparse hairlike fibers with attached mud particles and the shells of tiny animals. The intake and outflow openings are on opposite sides of the body. The intake opening is very muscular, turns inside out, and has six fingerlike bulges. The stomach is very large and occupies most of the animal's body.

Geographic range: Oligotrema sandersi (abbreviated to O. sandersi) sorberaceans live in the Atlantic Ocean.

Habitat: O. sandersi sorberaceans live in the deepest part of the ocean.

Diet: O. sandersi sorberaceans eat small invertebrates.

Behavior and reproduction: Scientists do not know how O. sandersi sorberaceans behave or reproduce.

Sorberaceans do not survive capture, and scientists have not directly observed their behavior. They do know that sorberaceans live alone rather than in colonies. (Illustration by John Megahan. Reproduced by permission.)

Oligotrema sandersi and people: O. sandersi sorberaceans have no known importance to people.

Conservation status: O. sandersi sorberaceans are not considered threatened or endangered. ∎
