Eckström's Topknot

Overview

Eckström's Topknot is a small, elusive, left-eyed flatfish belonging to the turbot family, Scophthalmidae. It is primarily found in the eastern Atlantic, ranging from the British Isles to Morocco, as well as in the western Mediterranean and the Adriatic Sea.

Appearance

This species features a relatively broad body and a small head, characterized by a distinct, deep notch located in front of the upper eye. Its dorsal and anal fins extend onto the underside of the body, creating noticeable lobes. The fish is typically pale brown in color, marked with irregular darker patches and a prominent dark blotch toward the tail.

Distribution & habitat

Eckström's Topknot is a demersal species that favors rocky substrates and rough ground, where it often clings to the undersides of rocks or steep slopes. While it is occasionally found on sandy seafloors, it is most frequently associated with complex, hard environments that provide excellent camouflage. Due to its preference for these rugged, difficult-to-monitor habitats, the species is often considered rare or under-recorded.

Biology & behavior

This fish is known for its secretive nature, often relying on its camouflage to hide from predators or ambush prey. It prefers crawling along the substrate to active swimming. Its diet consists of small fish and various invertebrates. The breeding season for this species occurs between February and August.
