Dwarf Chiton
intertidal          northern Mexico to northern Alaska          size to 16mm
They are not uncommon, but can be difficult to find due to their small size.  They are generally white or buff colored.  At lower tidal levels search under rocks resting on anoxic mud.  This is actually a species complex in the northern Pacific and is currently
under investigation (D.J. Eernisse, pers.comm.).
