Conasprella ione
Conasprella ione, common name the ione 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 Conasprella, these cone 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 40 mm and 76 mm. Distribution
This marine species occurs off Mozambique, Réunion, the Loyalty Islands, the Philippines, in the South China Sea; off Taiwan, Japan, New Caledonia and Western Australia. References
