Sharks are among the oldest vertebrate lineages in which their success has been attributed
to their diversity in body shape and locomotor design. In this study, we investigated the …

Sharks are diverse and ecologically important predators and are also highly varied in their
biology and behaviour. Prior studies have posited basic relationships between body form …

Body form can change across ontogeny, and can influence how animals of different sizes
move and feed. Scaling data on live apex predatory sharks are rare and, therefore, we …

The body form of sharks is notable for the distinctive heterocercal tail with external
morphological asymmetry present in most taxa and the ventrolateral winglike pectoral fins …

The scapulae of elasmobranchs project dorsolaterally from their fusion with the coracoid bar
of the pectoral girdle, serving as anchoring points for the cucullaris, trunk and appendicular …

The shark heterocercal caudal fin and its contribution to locomotion are of interest to
biologists and paleontologists. Current hydrodynamic data show that the stiff dorsal lobe …

Evolutionary relationships within and among different groups of sharks have long been
discussed by taxonomists, but phylogenies (evolutionary relationships) were originally …

Sharks vary greatly in morphology, physiology, and ecology. Differences in whole body
shape, swimming style, and physiological parameters have previously been linked to varied …

Pelagic sharks include oceanic and semi-oceanic species of sharks and rays, active
freeswimming species that live in the world's oceanic basins and over the continental and …

Seven demersal shark species belonging to six families, obtained from the southern
Mediterranean Sea, were selected as representative of different putative swimming modes …
