Dolium maculata Lamarck, 1822 |
Tonna dolium is a large species of sea snail or tun snail, a marine gastropod mollusc in the family Tonnidae, the tun shells.
[edit] Distribution
This species occurs in the tropical Pacific Ocean from Thailand and the Philippines south to northern New Zealand.
[edit] Shell description
The shell is globose, sculptured with rather narrow spiral corrugations, with interspaces almost twice the width of the corrugations above, but gradually lessening, to slightly less than their width on the lower base.
The colour pattern is very regular, consisting of rectangular reddish-brown maculations, confined to the corrugations, upon a cream background. The interior of the aperture is white, faintly tinged with pale brown. The outer lip is thin, without an internal variciform ridge.
The shell height is up to 82 mm, and width up to 72 mm.
