Rare appearances of bull sharks (Carcharhinus leucas) in river systems and other freshwater ecosystems have been reported from five continents. The wide geographic range this phenomenon, the physiological adaptations species to allow for movement into rivers, a fossil record Miocene Epoch, all imply that behavior has long history. In Mississippi River basin, however, only two specimens were cap...

Abstract Reef sharks, including blackfins ( Carcharhinus melanopterus ) reside in the lagoons and on outer slopes of barrier reefs Mo’orea Island, French Polynesia. In general are shallow enough to permit underwater observation, while dive clubs hold shark dives at different sites ocean. Thus, presence blackfin sharks especially, other species times, is confirmed daily. Between about 21 July 2 ...

Skin lesions caused by the ectoparasite Dermophthirius penneri Benz, 1987 (Monogenea: Microbothriidae) on 2 wild-caught blacktip sharks (Carcharhinus limbatus) from the northern Gulf of Mexico were studied using light and scanning electron microscopy. Grossly, lesions appeared as multifocal, well-demarcated, ovoid or irregularly shaped, light gray patches of skin. Scanning electron microscopy o...
