Key identification features
- Elongated, oval body with both eyes set close together on the right side near the top of the head
- Small, distinctly curved mouth positioned on the underside of the blunt, rounded head
- Thick, leathery skin covered in fine scales, giving a slightly rough texture
- Uniform grey-brown to sandy-brown mottled coloring with no bold spots
- Rounded pectoral fin on the eyed side often marked with a dark blotch near the tip
- Dorsal and anal fins run continuously around a rounded tail; typically 25-40 cm long
Common look-alikes
- Common dab – has a strongly curved lateral line and rougher, sandpapery scales overall.
- Solenette – a much smaller relative reaching only about 12 cm, with a more rounded outline.
- European plaice – larger mouth on top of the head and bright orange spots, unlike sole's plain coloring.
Where you'll see one
Dover sole live buried in sand or mud on the seabed of the Eastern Atlantic and Mediterranean, from shallow inshore waters down to about 200 m. They are most active at night, lying camouflaged and motionless on the bottom by day.
Frequently asked questions
How do I tell a Dover sole from a dab or other small flatfish?
Look at the mouth and head: Dover sole has a small, curved mouth tucked under a blunt rounded head, while dabs have a straighter mouth and a much more strongly curved lateral line.
Why is Dover sole hard to spot in the wild?
It buries itself in sand or mud and is mostly active after dark, so its plain mottled coloring and low profile make it very well camouflaged against the seabed by day.
