Differential sensitivity to capture stress assessed by blood acidbase status in five carcharhinid
2007; Thorpe and Frierson, 2009), indicating that the results for blacktip sharks could be useful for other carcharhinids
of similar size.
Total numbers of taste buds present in the carcharhinids
are some of the highest recorded for elasmo-branchs (9000-12,000 as opposed to 2000-4000 in other species), and these species have the largest total sensory areas (approximately 2,100,000 [micro][m.
Olfactory morphology of carcharhinid
and sphyrnid sharks--does the cephalofoil confer a sensory advantage?

The tiger shark is a large carcharhinid
shark widely distributed in tropical and subtropical waters.
Other species of note observed included goldflag snapper (Pristipomoides auricilla), greater amberjack (Seriola dumerili), large-head scorpionfish (Pontinus macrocephalus), dawn boarfish (Antigonia eos) (Randall, 2007), shortspine spurdog (Squalus mitsukurii), and numerous carcharhinid
The trend in marginal increment analysis indicated that band formation occurs once a year during winter months--a result common to most studies where relative marginal increment analysis is used for carcharhinid
The night shark (Carcharhinus signatus) is a deepwater coastal or semi-oceanic carcharhinid
that is found in the western Atlantic Ocean along the outer continental or insular tropical and warm temperate shelves, at depths exceeding 100 meters (Bigelow and Schroeder, 1948).
Although the conservation status of certain carcharhinid
species (Carcharhinus limbatus, C.
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).
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.
Gray reef sharks are carcharhinids
, related to blacktips and bulls.
