Conasprella iansa
Conasprella iansa 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 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 11 mm and 16 mm. Distribution
This species occurs in the Atlantic Ocean off the Abrolhos Archipelago, Eastern Brazil
