Pufferfish contain tetrodotoxin, a substance that makes them foul tasting and often lethal to fish. To humans, tetrodotoxin is deadly, up to 1,200 times more poisonous than cyanide. There is enough toxin in one pufferfish to kill 30 adult humans, and there is no known antidote.

This is a unique once in a lifetime dive spot - diving off an active volcano. The volcano itself last erupted in June 2005 and as a result you will find coral is sparse but to see bright tropical fish against the back-drop of black walls is surreal! Surrounded by some seriously deep water there are also regular reports of pelagics around Barren Island including Dog Tooth Tuna, Silver Tip Reef Sharks, Barracuda, Rainbow Runner, and Trevally.
