Conus sulcatus
Conus sulcatus, common name the grooved shell, 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 21 mm and 89 mm. The smooth shell shows revolving grooves crossed by longitudinal striae. The intermediate ridges are flat or rounded. The short spire is carinated, striate, sometimes with distant compressed tubercles. The ground color of the shell is light yellowish brown, or whitish.

Conantokin-Br is a toxin derived from the venom of Conus sulcatus.

Distribution
This marine species occurs off Japan, Taiwan, in the Bay of Bengal and off the Solomon Islands, New Caledonia and Queensland, Australia.
