Beech Cone, Conus betulinus

This common marine species inhabits the Indo-West Pacific region. It is often found on mud near river mouths, where it feeds on worms. Its large, heavy shell is covered in life by a thick brown skin that bears thousands of fine ridges. This protects the shell from drilling organisms and the dissolving effects of low-salinity water. Once it is removed, the characteristic pattern of spots and stripes is revealed.
