White Sand Macoma    Macoma secta



Found in the mid to low intertidal zones and to depths of 165 feet, the White Sand Macoma is one of several kinds of Macoma clams that lie protected under sandy sediments. 


The shell is a bright white with a shiny surface while living - part of it remains on the bottom of the shell in the photograph.  Their shells can grow to 5 inches although this specimen is a little over 2 inches.  They are distinguished from other similar clams by the ridges at the rear of the shell.


They burrow to depths of 8 to 18 inches below the surface and are distributed from central British Columbia to Baja California.
