Lined Sole, Achirus lineatus

The Lined Sole (Achirus lineatus) is a species of saltwater fish that is found in the Western Atlantic, and northern Gulf of Mexico south to northern Argentina. It occurs mainly in brackish or hyper-saline lagoons, or on sandy-muddy bottoms of estuaries as well as the littoral zone. It is sometimes confused with the Hogchoker (Trinectes maculatus).

The lined sole is defined by its ocular-side pectoral fin with 2 – 8 rays, and the blind-side pectoral fin with a single ray or none at all. It has a darkly shaded caudal region on the blind-side of the body and the face-side caudal fin with numerous dark irregular blotches.

It hides itself in substrate leaving its eyes uncovered to view prey and predators. It can easily camouflage itself against its environment. It feeds on worms, crustaceans and small fishes. The young feed on plankton for a short while. It has a very slow growth rate.
