Patterns of genetic connectivity can be used to define the geographic boundaries fishes and underpin management decisions. This study a multi-marker approach investigate population structure scalloped hammerheads (Sphyrna lewini) in Indo–Pacific. Samples from 541 S. lewini were collected 12 locations across analysed using two regions mitochondrial genome, nine microsatellite loci sets Single Nu...

Shark is a cartilaginous fish that widely hunted because it has high economic value. The waters of Aceh are directly adjacent to the Indian Ocean and Malacca Strait making preferred habitat for pelagic fish, especially sharks. Information on shark species landed in west east very limited due difficulties identification commonly used local names. This study aimed determine types sharks Banda Ace...

Whale sharks Rhincodon typus frequently appear to interact or associate with other species, which vary depending on the community structure and demographic of whale at each location globally. Here, we present species sighted around in Galapagos Archipelago reported by dive guides scientists also earlier publications. These associated include cetacean species: bottlenose dolphins Tursiops trunca...

Several factors that influence the evolution of the unusual head morphology of hammerhead sharks (family Sphyrnidae) are proposed but few are empirically tested. In this study we tested the 'enhanced binocular field' hypothesis (that proposes enhanced frontal binocularity) by comparison of the visual fields of three hammerhead species: the bonnethead shark, Sphyrna tiburo, the scalloped hammerh...

Although sharks have a fundamental role in maintaining the balance of aquatic ecosystems, exerting great influence on lower levels food chain, their populations are declining worldwide due, to large extent, overfishing. Of 64 species registered Ecuador, from January December 2019, 19 were recorded Manta 15,455 captured individuals, with family Carcharhinidae being most abundant catches (69.4%),...
