Description
Diplectrum radiale (Radial Sand Perch) is a small marine fish belonging to the family Serranidae (sea basses and groupers). In Spanish-speaking regions it is commonly known as Serrano.
Description:
The species has an elongated, moderately compressed body adapted for life near sandy bottoms. Its coloration ranges from light brown to yellowish-brown, marked with darker vertical bars and mottled spots that provide excellent camouflage against sand and sediment. Fine radial lines on the head give the species its name (radiale).
- Typical length: 15–20 cm
- Maximum length: approximately 25 cm
- Large mouth typical of serranids
- Continuous dorsal fin with spiny and soft portions
- Rounded to slightly truncate caudal fin
- Demersal predator feeding on small fishes and crustaceans
Diplectrum radiale is usually found resting on or hovering just above sandy or muddy substrates.
Distribution:
This species occurs in the western Atlantic Ocean, including Florida (USA), the Gulf of Mexico, the Caribbean Sea, northern South America, and along the Brazilian coast to southern Brazil.
It inhabits coastal marine waters, estuaries, bays, and shallow continental shelf areas, generally from shallow depths down to about 100 meters. The species prefers sandy and muddy bottoms where it can effectively camouflage and ambush prey.
