The Black-spotted Pufferfish, also called the Dog-faced Puffer, is native to tropical areas of the Indian and western Pacific Oceans.
It grows to 33cm or around a foot long. There is an off-white and a bright yellow form, both with black spots.
It is solitary and territorial.
Like all pufferfish, it can inflate its body like a ball to discourage predators. It also has a deadly toxin if eaten.
The teeth are for crustaceans, molluscs, other invertebrates, sponges, algae and coral.
