Wikipedia

Conus lividus

Conus lividus, common name the livid cone, is a species of sophisticated predatory sea snail, a marine gastropod mollusk in the family Conidae, the cone snails, cone shells or cones.

Like all species within the genus Conus, these snails are predatory and venomous. They are capable of "stinging" humans, therefore live ones should be handled carefully or not at all.

Contents

Description

The size of an adult shell varies between 25 mm and 81 mm. The spire is coronated, depressed conical. The lower half of the body whorl is distantly striated, and the striae sparsely granulous. The color of the shell is light yellowish or olivaceous to orange-brown. The tubercles of the spire and a band below the shoulder, as well as a central band on the body-whorl, are white. The base and the interior are violaceous. The epidermis is somewhat tufted in distant revolving series. [3]

Distribution

This cone snail has a very wide distribution. It is found in the Red Sea, in the Indian Ocean along Aldabra, Chagos, Mascarene Basin, Mauritius, Mozambique, Tanzania and the West Coast of South Africa; in the entire Pacific Ocean.[2]
