The shinyrayed pocketbook's shell is solid yet thin with a smooth and shiny surface. The coloring is light yellowish brown with fairly wide, bright emerald green rays over the entire length of the shell which may appear as darker brown in older specimens. Water and food are obtained by siphoning which provides phytoplankton, tiny zooplankton, and organic detritus.
