DESCRIPTION

A stunning 18.5cm long Giant Tonna seashell. At just 174g, it is quite lightweight for its size. It comes from a very large sea snail that lives in the Indo Pacific region. Try holding this shell over your ear and you will hear the relaxing sound of the ocean!

The conical spire is formed of six convex, very distinct whorls, loaded externally with wide, flat, slightly raised ribs, separated by narrow and superficial furrows. The whorls of the spire are isolated by a deep channeled suture. The body whorl is rounded and very ventricose. The aperture is large, subovate, colored interiorly with reddish, and marked with transverse ribs corresponding to the furrows without. The outer lip is dilated, undulated, tinged with black, or a deep brown upon the edge. The inner lip is whitish, spread out in a very thin plate upon the belly of the body whorl. The columella is smooth, polished, and forms at the left of the umbilicus a thick rib, marked by transverse striae, which terminates at the emargination of the base. The external surface of this shell is of a uniform reddish fawn color ; nevertheless the ribs are varied with wide spots or irregular brown and white blotches which are very remarkable.
