Conasprella longurionis
Conasprella longurionis 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 28 mm and 46 mm. Distribution
This marine species occurs off East Africa and from Taiwan to Sri Lanka
