cone snails
Toxic marine mollusks
Cone snails are marine mollusks with ornately patterned conical shells, found in warm tropical waters.
They hunt using a venomous harpoon-like tooth that can paralyze fish, worms, or other snails almost instantly.
Some species produce venom potent enough to kill humans, making them among the most dangerous mollusks.
Their toxins are studied for pharmaceutical applications, including pain management.
