However, the basic bauplan of the brachiopods is quite different from molluscs: the most obvious character is that the two valves are dorsal and ventral, whereas in the bivalves they are lateral. This partly accounts for the late segregation of the Brachiopoda from the phylum Mollusca in the middle of the nineteenth century.
