|PISCES : PLEURONECTIFORMES : Scophthalmidae||BONY FISH|
Description: Topknots are small, left-eyed flatfish with a broad body and head. The dorsal fin starts just above the mouth and both the dorsal and anal fins are joined to the tail fin. The background colour is beige-pale brown with irregular darker mottling. Running from each eye to the edges of the body is a distinctive dark band and there is a dark blotch behind the pectoral fin. Adult fish can grow to 25cm in length.
Habitat: The topknot is usually found beneath boulders or overhangs in rock on the low shore or on the sides of rock faces in the kelp forest.
Distribution: Widespread around the coasts of Britain and Ireland apart from the east coast of England where its apparent absence may be due to a lack of suitable rocky habitats.
Similar Species: Topknots and lemon sole are the only flatfish that live in rocky habitats however the lemon sole is right-eyed. Zeugopterus punctatus can easily be distinguished from other topknots by the darker band that runs across the eyes and by the shape of its head.
