Canthigaster amboinensis, also known as the Ambon Toby and Spider eye puffer, has a tropical Indo-Pacific distribution and is found from East Africa to the Galapagos Islands, north to southern Japan and Hawaii, south to the Great Barrier Reef and the Society Islands. Occurs in shallow outer reef areas, often in the lower reaches of the surge zone to depths of 10 m. Omnivorous; feeding on algae and a wide variety of benthic animals.
The Ambon Toby is brown dorsally on head and body shading to whitish ventrally with small pale blue spots on body and basally on caudal fin. Small dark brown spots on lower side mixed with blue, and blue lines radiating from eye. Numerous close set small pale blue spots or irregular lines on cheek.
Canthigaster amhoinensis is one of the faster swimming species of the genus. They have arepelling substance in their skin, which protects them from predators.
