The Potato Rockcod can grow to an alarming 2m in length, with a weight of about 100kg. In some areas it was common for divers to feed these large fish and this practice has resulted in some individuals boldly approaching divers underwater.
The Potato Rockcod is grey-brown with large dark brown spots on the body. It has small spots on the head and lines from the back of the eye.
The species grows to 2 m in length.
It occurs throughout Indo-West Pacific.
