Nucleotide-sequence variation at the cytochrome b locus was investigated in five Solea species, with a re appraisal of meristic data and a review of allozyme data pertinent to their systematics. Solea aegyptiaca, considered a synonym of Solea solea, and

Examination of morphometric characters of Solea aegyptiaca shows that it cannot be separated from Solea solea. Diagnostic characters are given to separate this species from S. senegalensis. The available data show that Solea impar and S. nasuta are junior

The genetic and morphologic variation of Solea lascaris (Risso, 1810) was studied along the Portuguese coast through protein electrophoresis and morphometric and meristic analysis. Genetic analysis was based on 10 loci, all except one polymorphic. The

Sand sole, Solea lascaris, were collected along the Portuguese coast, between October 2002 and July 2003, to examine feeding habits, age and growth and sexual cycle. The most important prey items were Mysidacea, Amphipoda and Polychaeta. Differences in
