Anomiidae - Jingle Shells

Anomiidae, the jingle shells, have shells that follow the shape of the object it lies on or within. It is roughly ovate, shiny, thin and translucent. The lower, attached right valve has a hole in the center from where the shell grew around its byssal threads (which are used to attach to hard surfaces). Color is usually yellowish to orangish. The upper, left valve is usually somewhat convex and has 3 scars on its underside (1 muscle and 2 byssal scars). The 2nd (anterior) muscle was "lost" over time. Although the flesh of the snail is bitter, the outer shell is used in the manufacturing of glue, chalk, paint, shellac and solder and as decorative objects. There are 2 species found in Texas waters.
