Also known as muddy flounder, popeye sole, and spot flounder, the C-O Sole belongs to the flatfish or righteye flounder family (Pleuronectidae). They are related to the Dover sole. Mexicans call them platija de fango.
C-O Soles are right-eyed; their eyes are large and bulbous and located near the tip of their snouts. A prominent ridge can be found between their eyes; their top eye occurs a little above their lower eye.
C-O Soles are generally muddy brown to black, though some may use camouflage and develop pink patches on their bodies to match their surroundings composed of pink coraline algae; most of the C-O Soles resemble the sandy bottom of the ocean. Their blind side is usually off-white in color. C-O soles have a distinctive dark spot on the middle of its upward-facing (eyed) side. Their anal fins have no spines but consist of 46 to 56 rays. Their dorsal fins extend to their heads and have 65 to 78 rays. Their caudal fins are rounded and deep. Mature C-O Soles lack swim bladders.
C-O Soles love benthic invertebrates and fishes. They also prey on amphipods, mollusks, bivalves, and small fishes. Their favorite crustaceans are shrimp, crabs, brittle stars, polychaetes, and clams. The juvenile C-O soles feed primarily on shell-fish and small, live fishes. Their feeding season runs from June to July and September. They spawn during early spring and late winter; female C-O Soles’ eggs float near the surface of the waters.
The C-O Sole can grow up to 14 inches in length and one pound in weight. Despite their size, C-O Soles have a high quality of meat; they are best cooked pan-fried because they are difficult to fillet.
