The California sheephead (Semicossyphus pulcher) is a wrasse native to the eastern Pacific Ocean. Its range is from Monterey Bay, California to the Gulf of California, Mexico. The sheephead can reach a size of 91cm and a weight of 16kg. The male is black with a white jaw and a broad red band spanning the body sometimes. The female is pink. The juvenile form is bright red with a black stripe spanning the body. All sheepheads are born as females and eventually change to males at 18 inches. The age of the transition depends on environmental factors such as food supply.
