Conus acutangulus
Conus acutangulus, common name the sharp-angled 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. Description
The size of the shell varies between 13 mm and 46 mm. Distribution
This species occurs in the Red Sea and in the tropical Indo-West Pacific; off Queensland, Australia. References
