Diel movements of the blacktip shark (Carcharhinus limbatus) in a Caribbean nursery
Environmental Biology of Fishes, 2018The blacktip shark (Carcharhinus limbatus) is a common coastal species in tropical and subtropical waters around the world. To examine the fine-scale movement ecology of this species in a Caribbean nursery, 17 neonate blacktip sharks were acoustically tagged in May, 2012 and tracked for one year in Coral Bay, St John, USVI.

Agonistic Displays in the Blacktip Shark (Carcharhinus limbatus)
Copeia, 2000Abstract Agonistic displays in the Blacktip Shark (Carcharhinus limbatus) were triggered by divers slowly ascending to the surface. Two locomotor elements, rolling and tilting, were identified. They closely resemble the behavior patterns of sharks trying to shake off Sharksuckers (Echeneis naucrates).

Journal of Fish Biology, 2018 This study reports on the metabolic rate of the blacktip shark Carcharhinus limbatus and the energetic costs of external tag attachment. Metabolic rates, swimming speed and tail-beat (BT) frequency were measured in a static respirometer with untagged ...

Postoncomiracidia of Dionchus sp. are described from specimens collected from the skin of 2 blacktip sharks Carcharhinus limbatus, captured in the northern Gulf of Mexico. The parasites resemble nonciliated oncomiracidia hatched from eggs laid by Dionchus sp.

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, 21âhydroxylase 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.

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 ...
