Larval and postlarval development of the window-pane shell, Placuna placenta L. (Bivalvia: Placunidae)
Share
Abstract
Stages of development of P. placenta from the straight-hinge veliger to the adult are described. Mature larvae metamorphose at lengths from 220-230 m. Larvae probably attach byssally to the water surface at metamorphosis and remain in the plankton for some time before finally settling on the mud bottom.
