Also known as Fluke, Flounder has brownish-green skin with faint red spots on the dark side, and is a bright white on the blind side. They are a similar shape to Halibut (though that’s where the similarities end!), and range in size from 350g to 900g.
Dabs tend to be smaller, and are rarely caught bigger than 680g. At their best, both are similar in flavour and texture to Plaice, and can be a good buy.
