13 photos - 5 species


There are over 675 species, 134 genera, 14 families and two suborders.

They are flattened, disc-like fish that lie with one side on the bottom.

Both eyes have "migrated" to one side during evolution.

They take on the colour of the substrate.

Depth: 1 - 15

Can drastically adapt their colouring to the ground, fading or darkening.

Their eyes are diagonal to each other.

They normally inhabit seagrass, coral rubble and sandy areas, lying motionless on the bottom. 

As they rely completely on their camouflage, a slow approach is possible.

Platichthys flesus

European flounder

Maximum length: 50 cm

Depth: up to 100 metres

Flatfish from Europe's coastal waters.

They prefer brackish water, but can also tolerate fresh water.

They are found in estuaries, bays and fjords.

They have a streamlined, strongly flattened body,

with the body width being less than half the body length.

About one third of flounders have their eyes on the left side,

the other two thirds on the right.

Similar to the plaice, it often has reddish, pale spots on its upper side.

They live at depths of up to 100 metres, usually buried up to their eyes.

They migrate into the sea to spawn.
