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.

The north tip of Island 7 is home to this fantastic boulder site. Descending in a bay to the west of the main site will put you in a coral garden filled with huge table corals with the chance of Green and Hawksbill Turtles, as well as Clown Trigger Fish, Butterfly Fish, and Damsel Fish. The main body of the site, marked with a buoy descending to around 14m, is made up of large boulders dropping off to the depths as the name might suggest. These boulders have formed many swimthroughs and canyons that have numerous soft corals growing around them. Though there is a good chance of Giant Trevally, Barracuda, White Tip Reef Shark, and Wahoo here, don't forget to look for treasures such as Ribbon Eels, Orange Spot Pipefish, and Roboastra Nudibranchs.
