Tonna sulcosa, common name banded tun, is a species of large sea snail, a marine gastropod mollusk in the family Tonnidae, the tun shells.[2]
Distribution
This species is widespread in the tropical Indo-Pacific region - from the Red Sea and the Indian Ocean to the Indo-China, the Philippines and Western Australia. [2][3][4][5]
Description
Shells of Tonna sulcosa usually can reach a length of 50–125 millimetres (2.0–4.9 in), with a maximum of 153 millimetres (6.0 in). [4] [5]These medium sized shells are quite strong, oval-globose, with 4 -5 moderately convex turns and flat ridges. The aperture is large, semi-circular, with reflected lip and long, sharp teeth.
The shell surface is white with 3 - 5 wide brown bands.[6]
Habitat
These benthic gastropods live on sandy bottoms in tropical environment at depths of 10 to 70 m.[5]
Life cycle
Embryos develop into free-swimming planktonic marine larvae (trocophore) and later into juvenile veligers. [5]
