Fish
Common Dab
Limanda limanda
On a sandy bay, a common dab lies flat and almost invisible, its upper side the exact colour of the sand it rests on.
Overview
The common dab, Limanda limanda, is a Least Concern flatfish of sandy bottoms in the north-eastern Atlantic and the North Sea, where it is one of the most abundant species. Its rough scales, arched side line, and small size make it easy to tell from larger flatfish such as the plaice.

Status
