Comments: There are e types of skeletal abnormalities observed on individuals caught in Sado estuary: dentary, vertebrae and hypural plates, with the latter the most common. These deformaties were more frequent in the industrialized bank of the estuary allowing the relationship between pollution and observed teratology; thus, the species may be considered a pollution indicator species (Ref. 45053). Found in Tagus estuary (Ref. 51031).

Korte beschrijving Morfologie | Morfometrie

Neck scaled with a black spot in the front end of each dorsal fin (Ref. 35388); body shape is terete, slightly depressed; eyes situated dorso-laterally; reduced swim bladders (Ref. 92840).

Found in estuaries, lagoons and inshore waters over sand or mud, in seagrass or on algae (Ref. 4696). Occasionally recorded in freshwater, but there are no documented records of actual occurrence in European freshwaters (Ref. 59043). Feed on crustaceans (larger amphipods, isopods, shrimps, mysids, small crabs), bivalves, gastropods, polychaetes, chironomid larvae, sometimes small fish (Ref. 4696).
