Typhlodaphne strebeli

Typhlodaphne strebeli is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae.

Description

The size of an adult shell varies between 15&nbsp;mm and 30&nbsp;mm. The elongate, ovate-fusiform shell has a buff color. It differs from Typhlodaphne purissima <small>(Strebel, 1908)</small> by being slender, having a smaller protoconch (1½ whorls) and showing flexuous, closely spaced, subobsolete axials (numbering 18 to 24) over the 5 whorls of the teleoconch. The shoulder is slightly concave. The narrowly ovate aperture has a rounded anterior end. Across the shell run numerous microscopic lirae.

Distribution

This marine species occurs along the Tierra del Fuego.
