The Papuan toby (Canthigaster papua) is a species of sharpnose puffer. It is one of the more colorful members of the puffer family and is also sometimes known as the false-eyed pufferefish. As with all puffers, the Papuan toby can inflate its body by taking in water. This makes it look larger to predators. The sharpnosed puffer can be found in the Indian and western Pacific oceans including New Guinea, Australia, Indonesia, and the Philippines. This species grows to a length of about 4 inches (10 centimeters).
