In this study, we identified a ghrelin-like peptide (ghrelin-LP) in two elasmobranchs. The peptide, isoforms and cDNA encoding its precursor were isolated from the stomach of two sharks, the hammerhead (HH) shark (Sphyrna lewini) and the black-tip reef (BTR) shark (Carcharhinus melanopterus).

On the island of Moorea, French Polynesia, tourism operators have engaged in consistent elasmobranch provisioning at specific sites since the 1990s, conditioning the area’s shark and ray populations to human feeding and developing profitable lagoon tours based on close-contact elasmobranch encounters.

During a survey of the population of blacktip reef shark Carcharhinus melanopterus in Moorea (French Polynesia) between 2007 and 2011, population structural characteristics were estimated from 268 individuals. Total length (LT) ranged from 48 to 139 cm and 48 to 157 cm for males and females, respectively, demonstrating that the average LT of females ...

This study examined the characteristics of a blacktip reef shark Carcharhinus melanopterus population in turbid coastal habitats through a multi‐year fishery‐independent sampling and tag–recapture programme. Results revealed a highly structured population comprised almost entirely of juveniles and adult females with individuals between 850 and 1050 mm ...

Range of electrosensory detection of prey by Carcharhinus melanopterus and Himantura granulata
Marine and Freshwater Research, 2001Elasmobranch fishes have a well developed electrosense that is used for prey detection. Research into the nature of bioelectric cues emitted by prey has, however, been neglected, and consequently the spatial context in which the electrosense operates to detect and home in on prey is not completely understood.

Suspected intestinal torsion in a blacktip reef shark (Carcharhinus melanopterus).
Journal of zoo and wildlife medicine : official publication of the American Association of Zoo Veterinarians, 1999A blacktip reef shark (Carcharhinus melanopterus) with a history of recurrent eversion or prolapse of the valvular intestine, arrived at the Steinhart Aquarium in June 1996 and was placed in a mixed species shark display. The eversion soon reappeared, and the animal became thin and anorexic.

Inadequate life-history information can compromise management of shark populations. The present study examined the life history of blacktip reef sharks (Carcharhinus melanopterus) from north-eastern Australia with predictions that they would show life-history patterns similar to those of other reef sharks species.

To investigate factors contributing to immediate mortality in gill-net-caught elasmobranchs, we caught and blood sampled a total of 64 sharks and rays. Blacktip reef sharks (Carcharhinus melanopterus) were the most commonly caught species and had significantly elevated plasma lactate (mean 23.3 mM) and potassium (mean 6.2 mM) concentrations following ...

In many fish and reptiles, gastric digestion is responsible for the complete breakdown of prey items into semi-liquid chyme. The responses of the stomach to feeding and to periods of fasting are, however, unknown for many lower vertebrates. We inserted data loggers into the stomachs of free-swimming captive adult blacktip reef sharks (Carcharhinus ...
