Dwarf Chiton
intertidal          northern Mexico to northern Alaska
very small species of less than 16mm in length
They are not uncommon, but can be difficult to find.  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.).
