Description

The imperial scaldfish is a small, left-eyed flatfish of the family Bothidae reaching about 25 cm. The slender, laterally compressed body has a long dorsal fin running along almost the entire upper edge. The species is sexually dimorphic: males have a distinct black spot at the rear of the pelvic fin, while females show only a faint grey mark. The imperial scaldfish lives on sand, mud and shell bottoms of the eastern Atlantic, from Scotland to Namibia, and the western Mediterranean, usually between 40 and 200 m. It feeds on small bottom animals and has only minor commercial value.
