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.

Named for the 3 distinct trees on Island 9 that denote the jumping point for the dive, this is often one of the highlights of the trip. After a negative entry and quick descent from the big boat you will find yourself among a large cluster of sloping boulders from 17m to well over 40m. Often considered the best chance of Leopard Shark on any site here, there are also Long Fin Bat Fish, Napoleon Wrasse, Unicorn Fish, and groups of Brown Marbled Grouper about. Heading across the sand to the main reef, you can see Kuhl's Rays, Spotted Garden Eels, and sometimes Leaf Fish. Beware though as several times throughout the season both Yellow Margin and Titan Trigger Fish lay their eggs in the numerous 'pits' here. Choose your route carefully!! Once on the gently sloping coral reef you will be astounded by the amount of life. Highlights can include Banded Sea Kraits, schooling Yellow Fin Barracuda, Milk Fish, Hawksbill Turtles, and large groups of Big Eye Snapper. This is a great reef for snorkelers to see what they are missing by staying on the surface!!
