Shark liver oils are rich in polyunsaturated fatty acids, especially the n3 moieties. Data on the liver fatty acids of sharks from African waters, however, are limited. Liver samples from sharks from the western Indian Ocean off the east coast of South Africa and those from the Atlantic Ocean and Gulf of Mexico were examined.

Size and sex segregation of aggregating blacktip sharks,
AbstractBlacktip sharks (Carcharhinus limbatus) form large seasonal aggregations numbering in the thousands. These aggregations are typically spotted from the air which makes it impossible to determine the sex and size distribution. We sampled C. limbatus that occur in large aggregations off the coast of southeast Florida.

Characterization of adrenal cytochrome P450c21 from the blacktip shark (Carcharhinus limbatus)
Journal of Experimental Zoology, 1995AbstractThe characteristics of cytochrome P450c21 (21 hydroxylase; E.C. 1.14.99.10) were determined in interrenal tissue from blacktip shark (Carcharhinus limbatus). Consistent with other vertebrates, 21‐hydroxylase activity was enriched in the microsomal fraction of the interrenal and was dependent upon a source of reducing equivalents.

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.

Environmental Biology of Fishes, 2002
I analyzed and quantified the behavior of blacktip sharks, Carcharhinus limbatus, irritated by sharksuckers, Echeneis naucrates, attached to their bodies. The sharksucker induced behavior patterns were divided into simple rotational patterns, expressed by body turns along their main axes (roll, yaw, pitch); and complex patterns (wiggle, shake, wind ...

AbstractNew approaches to abundance surveying utilizing unoccupied aerial vehicles (UAVs) are proving to be effective tools in marine and terrestrial environments. We explored UAV efficacy for surveys in the Galapagos Marine Reserve (GMR), where relative abundance patterns of juvenile sharks and subsequent classifications of putative nursery areas ...

Species-specific hematology and biochemistry reference intervals (RIs) provide a crucial diagnostic resource for veterinarians, researchers, and wildlife managers working with elasmobranchs. This study aimed to establish hematologic and biochemical RIs from a population of free-ranging, juvenile blacktip sharks (Carcharhinus limbatus) in the Galápagos ...
