Eckström’s topknot – Zeugopterus regius

Eckström’s Topknot, scientifically known as Zeugopterus regius, is a fascinating flatfish species found in the depths of the Atlantic Ocean. This unique creature boasts an intriguing appearance and intriguing lifestyle, making it a captivating subject for marine biologists and enthusiasts alike.

Description & Characteristics

Zeugopterus regius, commonly known as Eckström’s Topknot, is a relatively small flatfish, reaching a maximum size of 20.0 cm. Its body, like other flatfish species, is laterally compressed, with both eyes positioned on the same side of the head. Its coloration is predominantly brown, with a distinctive pattern of darker blotches and markings. The topknot, a small, fleshy projection located above the eyes, is characteristic of this species, giving it its common name.

Habitat and Occurrence

Eckström’s Topknot (Zeugopterus regius) is a demersal species, meaning it lives on or near the bottom of the seafloor. It is typically found inhabiting depths ranging from 10.0 meters to 180.0 meters. This species is primarily found in the northeastern Atlantic Ocean, inhabiting various marine zones, including the coastal waters of Europe and the North Sea. The Eckström’s Topknot is particularly prevalent in these regions, making it a familiar sight to marine researchers and divers in these areas.

Taxonomy

The species Zeugopterus regius is classified under the Class: Teleostei, which encompasses a vast array of bony fishes. It is further categorized within the Order: Pleuronectiformes, an order characterized by flatfishes with their eyes situated on one side of the head. Lastly, it belongs to the Family: Scophthalmidae, commonly known as the turbot family, which comprises a diverse group of commercially important flatfishes.

Feeding

The diet of Eckström’s Topknot (Zeugopterus regius) consists primarily of small fish, invertebrates, shrimps, and crustaceans. This demonstrates its adaptable nature, readily consuming a range of prey items available within its benthic habitat. It utilizes its flat, camouflaged body to blend in with the seafloor, patiently waiting to ambush unsuspecting prey, showcasing its effective hunting strategy.
