Even though the Cone Snail is wrapped in a beautiful shell, do not touch it if you see one! These adorable but deadly animals can be found in warm shallow waters near the equator. The snail has harpoon-like teeth that can bite anything that touches it. Once bitten, the snails release a venom called conotoxin. The toxin can do serious damage to your nerve cells and can even cause paralysis. Unfortunately, there is no antivenin on the markets yet.
