Scaldfish

The scaldfishes comprise a genus, Arnoglossus, of lefteye flounders. They are found in the Pacific, Indian and Atlantic Oceans, including the Mediterranean and Black Sea. They are entirely absent from most of the Americas; the only exceptions are A. coeruleosticta and A. multirastris found off Chile. The genus include both species found in shallow and deeper water. The largest species reaches 28 cm (11 in).^[2]
