The lambis lambis , pale yellow wing screw , Krabbe screw or Small devil's claw ( Lambis lambis ) is a screw from the family of the wing screw (genus Lambis ), which in Indopazifik is widespread.
features
The elongated egg-shaped and humped, humped, large, thick and heavy snail shell of Lambis lambis , which in fully grown snails reaches a length of about 18, sometimes up to 29 cm, has a pointed conical thread. On the broad, shiny edge of the mouth (including the siphon canal) there are 7 finger-like, lengthwise nodular appendages, the fingers at the ends being straight and the middle ones crooked. The surface of the case is white to light brown with reddish brown and brown spots, the smooth mouth rose red.
The snail has a clear sexual dimorphism , with the males being smaller than the females and having shorter finger processes at their mouth.
The common spider snail moves like other wing snails with the help of its claw-shaped, horny operculum . This sinks her into the substrate and then suddenly contracts her foot. In this way, the snail can move a greater weight than its own body weight.
distribution and habitat
The common spider snail occurs in the Indo-Pacific , in the Indian Ocean from the coast of East Africa eastward, around Madagascar , in the Persian Gulf , in the Pacific Ocean on the Moluccas and the Philippines , to Micronesia and eastern Melanesia , from southern Japan and Taiwan to the south Queensland ( Australia ) and to New Caledonia . It is missing in the Red Sea.
The snail is often found in coral reefs on sand and gravel as well as in mangroves , in the shallow water of the intertidal zone and a little below to a depth of about 5 meters. It is particularly found on red algae , on which it feeds.
Use and hazard
Lambis lambis is collected for its case, which is sold as jewelry.
