Ivory Cone

Conus eburneus

Conus eburneus, common name the ivory 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.

There is one subspecies: Conus eburneus crassus G. B. Sowerby II, 1858 represented as Conus eburneus.

Appearance

The size of an adult shell varies between 30 mm and 79 mm. The shell is white, usually with two or three light yellowish bands, marked with very dark brown revolving spots.

Distribution

This marine species is found in the tropical Indo-West Pacific from the coast of East Africa (off Madagascar and Chagos) to Australia (the Northern Territory, Queensland and Western Australia), Polynesia and the Ryukyu Islands (but not along Hawaii)

Status

IUCN: Least Concern

Habitat

Found on shallow sandy areas from 3-63 m.

Reproduction

Members of the order Neogastropoda are mostly gonochoric and broadcast spawners. Life cycle: Embryos develop into planktonic trocophore larvae and later into juvenile veligers before becoming fully grown adults.

Food

Coneshells are carnivorous gastropods which catch prey organisms such as fish and shellfish byt shooting a venom-containing harpoon-like radular tooth. This is also used as a defense mechanisms and their venom is so potent that it has caused human fatalities.

Uses

The venom peptides of cone snails are encoded by a large gene family, and can selectively bind to voltage-gated ion channels (Na+, K+ and Ca2+ channels) and to membrane receptors (nAChR, 5-HT3R, NMDAR). This has interest from the pharmacological point of view. For example, eburnetoxin produced by Conus eburneus has interest as vasoactive substance.
