Meet the groupers
The grouper heading downhill
The slow-moving, big-mouthed predators with some rather unusual abilities
With its stocky body, stooped profile and coating of dark spots, there’s no mistaking the humpback grouper. To make them even more peculiar, the young of this distinctive fish constantly swim with their heads facing down. Like other members of the family, the humpback grouper is able to change sex.
The humpback grouper is a naturally rare species, but its wild population is becoming even smaller. Fishing for food and the degradation of its habitat are reducing numbers, and its unusual appearance has made it popular with aquarium owners.
