Oldwife

It is native to reefs in the Indian and western Pacific Oceans, and to the coastal waters of Australia.

Originally classified with the butterflyfishes, it has a similar deep and compressed body but is easily distinguished by its silver-and-black zebra-striped coloration, and by its two prominent dorsal fins, the second of which is very long, sickle-shaped, and has poisonous spines. It grows up to 50 cm long.

Its common name refers to the sound it makes when caught, caused by it grinding its teeth.
