Dried Puffer Fish. Porcupine fish have the ability to inflate their body by swallowing water (or air) and become round like a ball. This increase in size (almost double vertically) reduces the range of potential predators to those with much bigger mouths. A second defense mechanism is provided by the sharp spines, which radiate outwards when the fish is inflated.

Birdbeak Burrfish Cyclichthys orbicularis occurs in tropical waters of the Indo-West Pacific from the Red Sea and East Africa to the Philippines, north to southern Japan, south to Australia and New Caledonia and in the Southeast Atlantic at the south coast of South Africa in a depth range from 9 to 170m, max. length 30cm. The nocturnal species inhabits clear protected reefs with sponge and algal habitats, staying often in large sponges during the day. Cyclichthys orbicularis occasionally occurs on reefs, but usually over sand and mud bottoms. The species feeds on hard-shelled invertebrates. Interestingly, this fish can puff up its body by ingesting water, transforming into a spiny ball as a defense mechanism, which reduces its mobility but deters predators. His chemical defense mechanism is more effective than the swimming away: Tetrodotoxin (TTX) is a potent neurotoxin found in various marine organisms, including Cyclichthys orbicularis. It can be lethal to non-resistant fish species. The estimated lethal dose of TTX in humans is around 2 mg of pure toxin. Even small amounts can cause severe symptoms. This specimen was encountered in the Lembeh Strait, North Sulawesi, Indonesia1°27'13.104 N 125°14'14.634 E at 13m depth
