Short Description from Oklahoma Wildlife Conservation:
The Louisiana Pigtoe (Pleurobema riddellii) is a rare freshwater mussel with a thick, inflated, triangular to sub-quadrate shell. The beaks are elevated well above the hinge line but are sometimes eroded. The external shell is without sculpturing and reddish-brown, dark brown, or black in color. The interior shell surface (nacre) is typically white, rarely peach tinted, and iridescent posteriorly.
Natural Habitat:
Shallow riffles/runs in medium-large streams/rivers with rock substrate or woody debris.
