Conus quercinus
Conus quercinus, common names the oak cone or the yellow cone, is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.

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.

Description
The size of the shell varies between 35 mm and 140 mm. The shell has a lemon-yellow color, with numerous fine, rather close, chestnut revolving lines. In old specimens the revolving lines become obsolete. The spire is rather elevated, with a concave outline. The shoulder of the body whorl is obtusely angulated.

Distribution
This species occurs throughout the Indo-Pacific including Hawaii, Republic of the Marshall Islands, French Polynesia, Fiji, New Caledonia, in the Red Sea, in the Indian Ocean off Aldabra, Chagos, the Mascarene Basin, Madagascar and Mauritius; off Eastern India, the tropical Indo-West Pacific and off Australia (Northern Territory, Queensland, Western Australia).
