“…This pattern requires one of a number of different potential isolating mechanisms : a method of active exclusion of the ' common ' form by the ' central ' form in the definitive host ; a seasonal and ecological exclusion or exchange of intermediate host species occurring in the central region only ; or an extreme feeding preference of Solea lascaris for a particular species of intermediate host when available in the environment. As for most of the Soleidae, S. lascaris feeds on a wide range of small invertebrates, their importance in the diet being defined by their abundance in the environment (Link et al 2005). The composition and seasonal variation of S. lascaris diet along the Portuguese coast found in this study, supported by findings of other investigations (Cabral et al 2002 ;A.…”

S U M M A R YDidymobothrium rudolphii (Cestoda : Spathebothriidea) was collected seasonally from the sand sole, Solea lascaris, off the northern, central and southern areas of the Portuguese coast. Morphological and molecular analyses were conducted in order to examine the possible existence of cryptic species and to facilitate the circumscription of their morphological boundaries. Data were compared between D. rudolphii specimens from each of the 3 geographical areas and 4 seasons, and principal components analysis of 18 morphological characters was used to detect differences. Two distinct genotypes were present with sequence divergences of 1 . 9% and 2 . 1% in the large subunit (lsrDNA) and second internal transcribed spacer (ITS-2) of ribosomal DNA (rDNA), respectively. The less common ' central' genotype was present only off the central area from summer to winter, whereas the ' common ' genotype was present throughout the year off the northern and southern areas, but only during spring in the central area. No sequence variation was found within each genotype. The presence of 2 distinct genetic entities was supported by morphological analyses, which showed the ' central ' genotype specimens to be more slender and elongate, although morphometric ranges overlapped considerably for most characters. Molecular phylogenetic analysis of 4 of the 5 known genera of the Spathebothriidea showed Spathebothrium to be the earliest branching lineage and the 2 genotypes of Didymobothrium formed a sister group to Cyathocephalus. The concordance of genetic differences with variation in host diet according to season and locality could account for sympatric speciation occurring in the central region of the Portuguese coast.

“…On the basis of their food spectrum, flatfishes can also be grouped in feeder classes. A comprehensive review of the current literature on trophic ecology of flatfishes and their feeder classes is provided by Link, Fogarty and Langton 21 . The species studied here are polychaete and small crustacean feeders (all four species), echinoderm feeders ( L. limanda ), and siphon tip and benthos feeders (all except for S. solea ).…”

Flatfishes bury themselves for camouflage and protection. Whereas species-specific preferences for certain sediments were previously shown, the role of scales in interaction with sediment has not been investigated. Here, scale morphology and sediment friction were examined in four European pleuronectiforms: Limanda limanda, Platichthys flesus, Pleuronectes platessa, and Solea solea. All species had different scale types ranging from cycloid to ctenoid scales. On the blind side, the number of scales is higher and scales have less ctenial spines than on the eye side. The critical angle of sediment sliding (static friction) significantly depended on the grain size and was considerably higher on the eye side. The effect of mucus was excluded by repeated measurements on resin replicas of the skin. Our results demonstrate the impact of scale morphology on sediment interaction and give an insight about the ability of scales to keep sand. Exposed scales and a higher number of ctenial spines on the eye side lead to an increase of friction forces, especially for sediments with a smaller grain size. Our results suggest that the evolution of scales was at least partly driven by their interactions with sediment which confirms the relevance of sediment for the distribution and radiation of Pleuronectiformes.
