Clavus unizonalis, common name the one-zoned turrid, is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.[1]
Description[edit]
The size of an adult shell varies between 15 mm and 26 mm. The shell is nodosely plicate, smooth, or with a few close revolving lines at the base. The color is whitish or yellowish white, the body whorl below the periphery chocolate, sometimes with a white band at the base. The color of the interior is chocolate, with an irregular white superior band.[2]
Distribution[edit]
This species occurs in the Red Sea, off northern Mozambique and in the demersal zone of the tropical Indo-Pacific off Mozambique, Japan, the Philippines, Indonesia, Papua New Guinea, the Solomon Islands, New Caledonia and the Loyalty Islands; also off Australia (Northern Territory, Queensland and Western Australia).
It has also been found in Pliocene strata of Papua New Guinea (age range: 5.332 to 2.588 Ma)
