The brown spotted reef cod (Epinephelus chlorostigma), known as Souman or Hamour-e Khaldar-e Qahvei in Persian and commonly as brownspotted grouper in English, is a fish belonging to the family Serranidae.
Spotted Cod can reach a length of 12–75 cm and a weight up to 7 kg. It is one of the largest coral dwelling fish. It has large pectoral and caudal fins that enable it to move and maneuver quickly through the water. It has a pale green grey body covered with small circular brown blotches, except for its belly which is lighter in color. When aroused, the fish is able to change its body shading according to its surroundings. Five dark brown vertical bands appear along the body. Its mouth is very large and capable of being opened to the width of the body diameter.
It feeds on crabs, cuttle fish and almost any other small fish. It is shy and lazy in its habits. When feeding, E. chlorostigma hides in its cave opening or in between corals and waits for some unsuspecting prey to pass by close enough to be pounced upon and swallowed whole. Predators are usually warned off by an impressive display of mouth gaping.
