Chicoreus palmarosae is a snail from the family of spiny snails (genus Chicoreus ) thatis widespreadin the Indo-Pacific . It feeds mainly on mollusks .
features
The narrow, spindle-shaped, elongated snail shell of Chicoreus palmarosae , which in adult snails reaches a length of 6.5 to 13 cm, has a long thread and is covered with three rows of very short, kinky-toothed rungs, with no and uneven cusps in the spaces between them . The mouth edge is serrated tightly on the columella. The case is orange-brown, striped horizontally and surrounded by brownish lines. The mouth is white, the tips of the sprouts purple-violet.
distribution
Chicoreus palmarosae occurs in the Indian Ocean around Madagascar , Mauritius , Chagos , Sri Lanka and the Mascarene Islands , in the Pacific Ocean to southwestern Japan .
habitat
Chicoreus palmarosae lives on coral reefs in the intertidal zone and below to depths of about 90 m.
food
Chicoreus palmarosae especially eats mussels . The shell of the prey is pierced with the radula under the action of acid and then the proboscis is guided through the hole to the flesh of the victim. Another possibility of attack is that the snail forces its proboscis through a gap between the shell halves or through the byssus opening .
Importance to humans
Chicoreus palmarosae , long known by Lamarck under the original name Murex palmarosae , is collected for its case, which is sold as jewelry.
