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]
