Mancinella armigera is a species of sea snail, a marine gastropod, in the family Muricidae, the murex snails or rock snails.[1][2] The species name means “bearing arms”.[3]
These large drupes have thick , spindle shaped shells covered by blunt tubercles, the aperture is yellowish brown.[3] But they are harmless to humans.[4] The shell is biconic, spire projecting and massive with two rows of projecting noodles on the last whorl, white in color with a yellow aperture.[5] The spire is projecting and acuminate, the suture is shallow.[5] There are eight axial ribs with two rows of prominent tubercles encircling the last whorl and a single spiral of tubercles on the other whorls, as well as a spiral sculpture of fine striae.[5] The aperture is ovate, the outer lips slightly thickened, with six denticles and a columella with a single absolute plait and a moderly developed siphonal fasciole.[5] The shell is often covered with a thick calcareous deposit.[5] The size of an adult shell varies between 50mm and 105.5mm. The shells are typically covered with a pink coralline algae.
This species is a non broadcast spawner. Life cycle does not include trochophore stage. [4]
This species is distributed in the Indian Ocean along Chagos, the Aldabra Atoll and Tanzania; in the Pacific Ocean along Japan.
These gastropods occur at the outer edge of fringing reefs and subtitle lava shoulders exposed to heavy wave action.[5] They are common along some exposed rocky coasts at depths of 10-40ft[3] and they often occur in pairs.
Collected for food by coastal populations.[4]
