Description

Zeugopterus punctatus is a small left-sided flatfish that is almost completely round in shape, with a broad body relative to its length. It is a mottled brown and white colour, a dark bar through the eyes,[2] light wide fins all the way round its body and a very small tail. Unlike most other flatfish, the Zeugopterus punctatus does not seem to change colour for camouflage but relies on immobility to avoid detection. Zeugopterus punctatus grows to a maximum length of about 25 cm. It is sometimes confused with the lemon sole Microstomus kitti which can be found on rocky substrates too but has a noticeable pattern on its back, does not have such long fins and is a more pointed shape.[3] The eyed side is covered in small ctenoid scales while the blind side has cycloid scales, the many small ctenoid scales feel downy to the touch.[2]

Distribution

The eastern Atlantic Ocean including the North Sea, Baltic Sea, English Channel, Bay of Biscay south to the coast of Portugal.[4]

Biology

This species lives along coastlines. It is unusual among European flatfish in that it prefers a rocky substrate. It has the ability to remain immobile in the most surprising sites, holding on to vertical rocks or even upside down under overhangs. This is achieved by using its broad fringing fins to fit itself into the substrate. Spawning takes place between February and June.[2]

It is carnivorous, feeding on small fish and crustaceans.[5]

gollark: I also had an invisibility cloak for unrelated reasons, but I don't know if the dragon cared about that. It didn't do any useful counterattack.
gollark: I don't believe in "TiCon Laser Gun".
gollark: You could also use one of the RA multishot bows or probably mining lasers.
gollark: I just exploded them repeatedly with Psi.
gollark: Really? They seemed very easy to kill.
