This feature also allows one to distinguish between this species and the common sole; the latter has a neat black spot close to the margin of the pectoral fin instead.

[6] The Selegalese sole originally occurred only in the eastern Atlantic, from southern Great Britain and Ireland (where it is rare) to Angola, including the Canary Islands.

Females attain sexual maturity at around 3 years of age and may reach a total length of 30 cm.

Spawning takes place during the summer, peaking in June around the Iberian Peninsula, when the water temperature is between 15 °C and 20 °C.

[4] In Europe, both the common and the Senegalese sole are landed and marketed, and there is little distinction made between them in official statistics.
