The potato grouper (Epinephelus tukula), also known as the potato cod or potato bass, is a species of marine ray-finned fish in the family Serranidae, which includes the groupers and sea basses. This species is found in the Indo-Pacific region and is known for its distinctive appearance and large size.

Description

The potato grouper is a large fish, capable of reaching lengths of up to 2 meters (6.6 feet) and weighing as much as 110 kilograms (240 pounds). It has a robust, elongated body with a broad head and a large mouth. The coloration of the potato grouper is typically greyish-brown with numerous dark spots that resemble the appearance of a potato, hence its common name.

Distribution and Habitat

The potato grouper is distributed throughout the tropical and subtropical waters of the Indo-Pacific region. Its range extends from the Red Sea and the eastern coast of Africa to the western Pacific Ocean, including areas such as Australia, Japan, and Fiji.

This species is commonly found in coral reefs, rocky areas, and lagoons, typically at depths ranging from 10 to 150 meters. Potato groupers are often seen in areas with strong currents, where they can be found resting on the substrate or swimming slowly along the reef.

Behavior and Ecology

Potato groupers are solitary and territorial fish. They are known to be curious and may approach divers, making them a popular subject for underwater photography. These groupers are ambush predators, feeding primarily on fish, crustaceans, and cephalopods.

The potato grouper is a protogynous hermaphrodite, meaning individuals are born female and may later change to male. This sex change is often associated with changes in social structure or size.

Conservation Status

The potato grouper is currently listed as Near Threatened on the IUCN Red List due to habitat degradation and overfishing. The species is targeted by commercial and recreational fisheries, and its large size makes it particularly vulnerable to overexploitation.
