Murex trapa, common name the rare-spined murex, is a species of sea snail, a marine gastropod mollusc of the family Muricidae, the rock snails. [1]
This species is widespread from Madagascar and Mascarene Islands, South-Eastern India, Sri Lanka and the Andaman Sea to southern Indonesia, Philippines, Taiwan and Southern Japan. [2] [3]
Murex trapa can be found in demersal, sandy habitats.
Shells of Murex trapa can reach a length of 50–124 millimetres (2.0–4.9 in), with a diameter of 8–21 millimetres (0.31–0.83 in). [2]
These moderately large shells are fusiforms or club-shaped, with height and acute spire and prominent spiral ridges. Shell surface is normally light brown or blue-gray with some yellowish-brown on spines. The body whorl shows three spiny varices. The aperture is lenticular, with a white interior margin and deep red-brown within. The outer apertural lip is crenulated. The sipholal canal is straight and moderately long (about 13–47 mm). Three to four short spines are restricted to the basal half of siphonal canal. [4] [5] [6]
The rare-spined murex is an active predator, mainly feeding on other molluscs and barnacles. [6]
Muricidae is a large and varied taxonomic family of small to large predatory sea snails, marine gastropod mollusks, commonly known as murex snails or rock snails. With over 1,700 living species, the Muricidae represent almost 10% of the Neogastropoda. Additionally, 1,200 fossil species have been recognized. Numerous subfamilies are recognized, although experts disagree about the subfamily divisions and the definitions of the genera. Many muricids have unusual shells which are considered attractive by shell collectors and by interior designers.
