About Blackspotted puffer

The blackspotted puffer (Arothron nigropunctatus) inhabits the subtropical and tropical seas. It lives on coastal and reef sites at a depth of 3 to 25 m. The fish is solitary and lives at the same territory. During the day, it can be seen resting on the top of the reef with tail tucked at the side. The fish contains the deadly poison tetrodotoxin, which protects against predators. Like other puffers, Arothron swells twice and takes the shape of a ball during an emergency.
Arothron has four tooth plates with fangs in its mouth, which continue to grow and need grinding. They help to feed on sponges, algae and chew the ends of branched corals. The fish also eats invertebrates, washing away the upper layers of sand with a stream of water from the mouth.
The color of the fish can be yellow, white, grey or blue, with black spots. The body is spherical, slightly elongated. The skin has no scales. There is no pelvic fin. The small dorsal and anal fins are located at the end of the body. The snout is short, with a pair of nostrils.
