Epinephelus marginatus
Grouper is a large fish that lives in the ocean. It has a big mouth and likes to hide in coral reefs. Grouper fish come in different colors like red, brown, and yellow.
Habitat: Coastal areas
The Grouper has a robust, oblong body often mottled with shades of brown, grey, or reddish-orange, helping it blend into rocky reefs. It possesses a very large mouth and thick lips, with small eyes set high on its head. Its camouflaged patterns make it visually distinct from fast-swimming open-ocean fish.
