Conus daucus explained

Conus daucus, common name the carrot 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.

There is one subspecies Conus daucus riosi Petuch, 1986

The minimum recorded depth for this species is 0 m; the maximum recorded depth is 120 m.^[1]
