Cone Snail Hunting and Toxins

The video explores the fascinating yet deadly nature of cone snails. Despite their harmless appearance, these ocean creatures are equipped with a siphon, eyestalks, and a deadly prascus. The prascus contains a harpoon loaded with a complex neurotoxic mix, making it one of the most toxic creatures with no known antivenom.
