Shell of the Week: The Hexagonal Murex

Murexsul oxytatus(M. Smith, 1938) reaches 40 mm (about 1.6 inches). The shell is lozenge-shaped, and the shell sculpture includes about 7–8 raised ribs per whorl, each rib bearing a number of sharp, fluted projections. The color is variable, ranging from white to salmon pink. The interior of the aperture is usually white.
