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 gently sloping offshore reef and is a nice, relatively shallow dive. The bottom on Minerva Ledge is mostly rock, with some healthy hard and soft corals. The top of the reef is at around 8m or 9m and is teeming with small fish. Many reef fish are in evidence on the reef itself, as are pelagics ; keep your eyes open for large Potato Groupers, White Tip Reef Sharks, schools of Blue Fin Trevally and serveral species of Bat Fish.
