AbstractThe inferior lobes of the shark hypothalamus were examined with light, transmission and scanning electron microscopy. The cells bordering the floor of the lateral recess appear to be typical liquor‐contacting neurons. With scanning electron microscopy (SEM) the apical ends of these cells are seen to bulge into the ventricular lumen. In contrast,

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 ...

An Observation of Mating in Free-Ranging Blacktip Reef Sharks, Carcbarbinus melanopterus
Pacific Science, 2010Abstract: We describe the mating behavior of free-ranging Blacktip Reef Sharks, Carcharhinus melanopterus, at Palmyra Atoll. This is the first primary report of mating in C. melanopterus and the first direct observation of mating for an obligate swimming shark 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 ...

Aquatic Conservation: Marine and Freshwater Ecosystems, 2013
ABSTRACTConnectivity between coastal habitats and mid‐shelf and offshore coral reefs is a topical issue in the conservation and management of fishes and coastal ecosystems.Coastal habitats provide a range of ecosystem functions for sharks and rays and the use of coastal ecosystems by these species affects conservation and management outcomes.

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.

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.

article i nfo Animal movements, residence times, and subsequently foraging strategies, should vary with habitat quality. We used acoustic and satellite telemetry, as well as stable isotopes, to look at movement patterns, macro- scale habitat use, and trophic ecology of blacktip reef sharks, Carcharhinus melanopterus, between two lagoons (eastern and ...
