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

[3] 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.

The size of an adult shell varies between 50 mm and 222 mm.

This marine species occurs in the Indian Ocean off Aldabra, Chagos, Madagascar, the Mascarene basin, Mauritius, and Tanzania; in the entire Indo-Pacific Region; off Australia (Northern Territory, Queensland, Western Australia).
