What is a brachiopod? Article published in three parts in the Geological Magazine Volume (2) 4 Pages 145-155, 199-208 and 262-273.

Brachiopod shells come in a variety of shapes and sizes. Sometimes the bottom valve is convex like the top valve, but in many species the bottom valve is concave or occasionally conical. In some brachiopods, the top valve is concave and the bottom is convex. The outer surface of the valves may be marked by concentric wrinkles or radial ribs.Study with Quizlet and memorize flashcards containing terms like What was the first Animal?, What is a mollusk?

Brachiopods feed on minute organisms or organic particles. Articulate brachiopods, which have a blind intestine, may depend partly on dissolved nutrients.

Traditionally, brachiopods have been separated into two major groups: the Inarticulates (brachiopods with phosphatic shells) and Articulates (everything else)., Brachiopods are solitary creatures that inhabit the seafloor across a variety of habitats.
