Linatella caudata, common name : the Girdled triton or Poulsen's Triton,[2] is a species of predatory sea snail, a marine gastropod mollusk in the family Ranellidae, the triton snails, triton shells or tritons.[1]

Distribution

This species is very widespread (but uncommon). It is present in European waters, in the Mediterraneal Sea, in the Western Atlantic from South Carolina to Brazil, in the Canary Islands, Cape Verde, in the Red Sea and in the Indian Ocean along Tanzania and in the Indo-West Pacific as far north as southern Japan.[1][3][4]

Habitat

These sea snails are usually found in seagrass meadows. They live only on soft substrates on the shelf at depths of 20 to 200 m.[5][6]

Description

The size of an adult shell varies between 35 mm and 100 mm. These medium sized shells are extremely variable in size, thickness, prominence, quantity of flare of the outer lip and thickness and width of the inner lip. Also very variable are the spire height and the intensity of the surface coloration. Commonly they have an hairy appearance and are solid and thick and show a Tonna-like form and moderately tall spire, with a very weak sculpture of low, weakly convex surfaced, spiral cords. The whorls are weak shouldered. They lack obvious varices or only the terminal varix is developed. The outer lip is flared and slightly thickened, with weakly shouldered whorls. The anterior siphonal canal is moderately long.

The interior of outer lip flare has sixteen low transverse ridges. The exterior surface of the shell varies between cream to pale yellowish-brown, with irregular, narrow light and darker bands. The body of these sea snails are brownish with black spots.[5][6][7][8]

Biology

These sea snails have been reported as feeding on Fan Shells (Pinna bicolor) and on the pearl oyster (Pinctada imbricata). Consequently they are considered a serious problem for the aquaculture of marine bivalves.[5][9]
