- Bigtooth Twinspot Flounder Pseudorhombus diplospilus Norman 1926 Actinopterygii > Pleuronectiformes > Paralichthyidae > Pseudorhombus A brown left-eyed flounder with four double ocelli arranged in a square on the upper side.
- Spiny Flounder Pseudorhombus spinosus McCulloch 1914 Actinopterygii > Pleuronectiformes > Paralichthyidae > Pseudorhombus
- Peacock Flounder Pseudorhombus argus Weber 1913 Actinopterygii > Pleuronectiformes > Paralichthyidae > Pseudorhombus A brownish flounder with five large ocelli on the eyed-side - two above and below the lateral line and one on the rear third of the straight part of the lateral line, and many dark spots and rings scattered on the body and median fins.
- Longlure Flounder Asterorhombus filifer Hensley & Randall 2003 Actinopterygii > Pleuronectiformes > Bothidae > Asterorhombus This pale brown flounder is covered in a finely mottled pattern of pale and dark spots and larger dark-edged brown blotches, and with dark blotches or short bars separated by white spots on the bases of dorsal and anal fins. The first dorsal-fin ray is elongate and separated from the rest of the dorsal fin. It comprises a central stalk and a narrow-smooth-edged membrane., and is used as a lure to attract prey of small fishes and crustaceans.
- Angler Flatfish Asterorhombus cocosensis (Bleeker 1855) Actinopterygii > Pleuronectiformes > Bothidae > Asterorhombus A flounder with an elongate first-dorsal-fin ray comprised of a bare stalk and a leaf-like membrane distally on ray - thought to resemble a shrimp or small fish. The Angler Flatfish is pale brown and finely mottled with paler and darker spots, and larger widely spaced blackish blotches (surrounded by small white dots).
- Leopard Flounder Bothus pantherinus (Rüppell 1830) Actinopterygii > Pleuronectiformes > Bothidae > Bothus A brownish to greyish left-eyed flounder with dark spots and dark-edged pale spots and florets on the eyed-side, and a large dark blotch on the straight section of the lateral line towards the rear of the body. Males have elongate pectoral fins used in territorial and courtship displays. Video of a Leopard Flounder in the Red Sea.
- Fison's Flounder Arnoglossus fisoni Ogilby 1898 Actinopterygii > Pleuronectiformes > Bothidae > Arnoglossus A sandy-grey flounder with numerous small, darker ocelli on the eyed-side, a narrow yellowish band along the base of the interspinous rays of the dorsal and anal fins running parallel with the upper and lower profiles of the body, and small darker and lighter spots on the fins.
- Blotched Flounder Asterorhombus intermedius (Bleeker 1866) Actinopterygii > Pleuronectiformes > Bothidae > Asterorhombus A brown mottled flounder with three rows of pale black-edged spots - along the lateral line, and along the dorsal and ventral body margins, and an elongate first dorsal-fin ray separated from the rest of the fin with a narrow fringed membrane along the outer half to two-thirds of the ray.
- Deep Flounder Pseudorhombus elevatus Ogilby 1912 Actinopterygii > Pleuronectiformes > Paralichthyidae > Pseudorhombus A relatively deep-bodied brownish flounder with a dark blotch at the junction of the straight and curved parts of the lateral line, a smaller blotch on the lateral line on the rear of the body and another on the anterior end of the caudal peduncle, dark rings following the dorsal and ventral profiles, and small dark spots and elongate markings on the median fins.
- No Photo Available Threespot Righteye Flounder Samariscus triocellatus Woods 1960 Actinopterygii > Pleuronectiformes > Samaridae > Samariscus Samariscus triocellatus is a small slender righteye flounder with a mottled brown body and three dark-edged ocelli along the lateral line. It usually lives on rubble and sandy bottoms of coral reefs. As it slowly moves across the bottom, it is well camouflaged to resemble a flatworm, sometimes waving its black pectoral fin.
