Grouper fish are stout-bodied, large-mouthed marine predators found mainly in coral and rocky reefs. They are known for ambush hunting and can grow over a meter long, playing a crucial role in reef ecosystems.
Scientific Name
Varies by species (common genera include Epinephelus, Mycteroperca)
Habitat
Found in coral reefs, rocky structures, and mangrove habitats across tropical and subtropical marine environments.
Conservation
Vulnerable – many species face overfishing pressure due to slow growth and group spawning behavior.
Lifespan
20–50 years depending on the species and environment.
Fun Fact
Groupers have been observed teaming up with moray eels to cooperatively hunt prey – a rare example of interspecies teamwork in fish.
Diet
Carnivorous – preys on fish, octopuses, and crustaceans using ambush tactics and suction feeding.
Average Size
Some species can grow over 1 meter (3.3 ft) long and weigh over 100 kg (220 lbs).
