2007; Thorpe and Frierson, 2009), indicating that the results for blacktip sharks could be useful for other carcharhinids
of similar size.
Given that the gestation period lasts 12 months, it is possible that tiger sharks may have the typical carcharhinid
biennial reproductive cycle, but this remains to be demonstrated.
Age was assigned by assuming an annual pattern of deposition, as commonly occurs for most carcharhinids
Electrophoretic analysis of phylogenetic relationships among Australian carcharhinid
The blue shark (Prionace glauca) is a large pelagic carcharhinid that is widely distributed in the world's oceans Throughout its range, it is considered the most abundant species of large shark (McKenzie and Tibbo, 1964; Casey, 1982).
We believe that the validated vertebral interpretations generated during this study for the first four years of growth, combined with the vertebral counts and longevity estimates from tag-recapture data, provide vigorous estimates of age and growth for a large pelagic carcharhinid, the blue shark.
The Atlantic sharpnose shark (Rhizoprionodon terraenovae) is a small carcharhinid
that inhabits the coastal waters of the western North Atlantic from the Bay of Fundy to the Yucatan (Castro, 1983).
The lowest fish bycatch in the WIO tuna purse-seine fishery was taken from free schools (mainly carcharhinid
sharks and Mobulidae rays) (Figs.
Interspecific competition for food amongst reef-dwelling, carcharhinid
species has been recorded (Nelson and Johnson, 1980), as have apparent interspecific hierarchies comprising 1) the silvertip shark, Carcharhinus albimarginatus, the Galapagos shark, C.
falciformis, only the right ovary is functional, as in most carcharhinids
God of the Holocaust heaps; of carcharhinids

On the basis of numbers of teeth recovered, the Hardie Mine shark fauna was dominated by carcharhinids
with Negaprion being the most common taxon.
Odontaspids are also characterized by lanceolate teeth and the lack of nictitating lower eyelids, which differentiates them from similar families such as the scyliorhinids (cat sharks) and carcharhinids
(requiem sharks) (Bass et al.
Rhynchobatids (71% of the elasmobranch catch), carcharhinids
(12%) and dasyatids (11%) dominated the catch (Pender et al.
acronotus are represented in catches from various inshore fisheries and carcharhinids
typically are characterized by low rates of population increase, adequate information about their reproductive cycle is required to facilitate management of stocks.
