Conantokin-E is a toxin derived from the venom of Conus ermineus. It is a fishing eating species. Utilizes specialized hollow harpoon like radula tooth to harpoon small fish and paralyze them with venom to facilitate swallowing.

Habitat

Minimum recorded depth is 0 m. Maximum recorded depth is 101 m.

Venom

Conus ermineus is a venomous species and capable of stinging humans, so it should be treated with caution. A delta-conotoxin (delta-EVIA) isolated from the venom of C. ermineus inhibits the inactivation of vertebrate Na + neural channels.
