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.

On the opposite side of Island 7 to East of Eden this lesser known site is named for the constant squeaking that can be heard at points along the reef as the huge boulders gently move in the swells. As the site is hit by large waves through the monsoon, corals here are far less numerous than many other sites, but it is a haven for Kuhl's Rays, Jenkins Whip Rays and our resident Porcupine Ray, Charles. The rubble is also a great place to find purple Hypselodoris Nudibranchs, Moray Eels, and Banded Sea Kraits. There are some wonderful oasis' of soft corals and sponges that are home to Spiny Lobsters and Clarks Anemone Fish as well as large boulders where you can see White Tip Reef Sharks, Green Turtles, Hawksbill Turtles, Giant Trevally, and Unicorn Fish.
