Large, mobile predators may act as spatiotemporal drivers of ecosystem processes by using diverse habitats and resource pools. Movement is a critical component of the role predators play as it reveals which habitats they use, which...
The international shark fin trade remains a major driver of shark overexploitation, yet the effectiveness of regulations under the Convention on International Trade in Endangered Species (CITES) remains uncertain. The pelagic thresher...
Sink your teeth into a light continental breakfast while you learn about our favorite finned friends and Mote’s breakthrough shark research. During this program, you'll meet our resident sharks and have all of your shark questions...
SEA Me Read: Celebrating the Shark Lady's 104th Birthday! Dive into the extraordinary world of Dr. Eugenie Clark, the pioneering marine biologist known as "The Shark Lady," in this special day-after birthday edition...
Mote Marine Laboratory scientists have published new research demonstrating that an electronic pulse device (EPD) can effectively deter and delay sharks from taking fish off fishing lines — a breakthrough that could help reduce shark...
Sharks and rays are vital to ocean health, but 75 percent of shark species are now threatened with extinction. Discover how Mote’s decades of research, from Dr. Eugenie Clark’s pioneering work to today’s Global FinPrint Project,...
The rapidly expanding use of high-resolution data-loggers to study marine vertebrates presents a wealth of new opportunities for understanding the behavior, physiology, and ecology of these animals in situ. It also presents a number...
Two sharks were trained to feed at a target which, when pressed, caused a submerged bell to ring. Later they were trained to press the target for remotely placed food. They retained this conditioned response after a 10-week period...
The scalloped hammerhead Sphyrna lewini and the great hammerhead S. mokarran are large, coastal to semi-oceanic shark species common to waters of the US east coast where they are regularly taken in commercial and recreational fisheries, particularly...
The blacktip shark (Carcharhinus limbatus) is the most commonly captured species in the Florida recreational shark fishery. We aimed to quantify the postrelease mortality of blacktip sharks and to determine whether hook type (circle or...
A number of international and national organizations, both governmental and non-governmental, have jurisdiction or influence over the management of marine fisheries, and hence, over the legal collection of elasmobranchs. It is the...
Thrilling underwater photographs enrich this unique guide to the shallow-water sharks of Florida and the Bahamas. Agile, sleek, and precise, sharks display many qualities we can admire and appreciate. These marvels of evolution have...
The ability to produce estimates of the metabolic rate of free-ranging animals is fundamental to the study of their ecology. However, measuring the energy expenditure of animals in the field has proved difficult, especially for aquatic...
Guatemala, situated in Central America along the eastern Pacific Ocean and the western Caribbean Sea, is a major regional consumer of elasmobranch (shark and ray) meat during the Roman Catholic Lenten season. Elasmobranch meat is supplied...
Populations of sharks, including those inhabiting coral reefs, have experienced dramatic global declines. Setting appropriate targets for restoring reef shark populations requires estimates of expected relative abundances in the absence...
In ecosystems, sharks can be predators, competitors, facilitators, nutrient transporters, and food. However, overfishing and other threats have greatly reduced shark populations, altering their roles and effects on ecosystems. We review...
