Over the last several decades, advances in telemetry have greatly expanded our ability to track where sharks go and when, but are limited in their ability to provide insights into specific behaviors or reasons for using particular...

Most reef fishes are site-attached, but can maintain a broad distribution through their highly dispersive larval stage. The whitetip reef shark (Triaenodon obesus) is site-attached, yet maintains the largest Indo-Pacific distribution...

The importance of habitat use studies has been increasing over the past decade. The recognition of the need to define and understand essential fish habitat for commercially fished species, and critical habitat for endangered species,...

Sharks are practically legendary for their sensory capabilities, with some of this reputation deserved and some exaggerated. Accounts of sharks being able to smell or hear a single fish from miles away may be fish stories, but controlled...

The first edition of Biology of Sharks and Their Relatives included a chapter describing the immune system of sharks, skates, and rays (Luer et al., 2004) in terms of the cellular components and tissue sites involved, an overview of...

Despite being a common apex-level predator on coral reefs throughout the tropical IndoPacific, surprisingly little is known about whitetip reef shark (Triaenodon obesus) movements and biology. This study used photo-identification from community-contributed...

An investigation into the separation control mechanisms found on the skin of fast-swimming sharks, with a particular focus on the shortfin mako (Isurus oxyrinchus) which is considered to be one of the fastest pelagic shark species,...

Despite often being considered top predators, small delphinids (2.5 m total length) in several marine ecosystems around the globe. Yet, estimating relative shark predation pressure and risk to cetacean species and populations, and...

The remarkable pace of advancements in technology, particularly in the last two decades, has contributed to the development of a toolbox that greatly enhances the range of investigations into the biology and life history of elasmobranchs....

Once abundant across all tropical and subtropical ocean basins, oceanic whitetip sharks (Carcharhinus longimanus) have experienced major population declines, resulting in the species now being listed as “Critically Endangered”...

Fishers losing their catch or gear to marine predators (‘depredation’), including sharks, is a growing problem around the world. Several types of devices have been tested to deter sharks from engaging in depredation but with limited...

Animals may demonstrate area-restricted search (ARS) behaviour when encountering prey, where they turn frequently to remain in an area where the probability of finding additional prey is relatively high. We would expect optimally foraging...

Sharks and other top predators have a substantial impact on their ecosystems through trophically mediated effects, and understanding the scope of this impact is essential to forming an accurate picture of energy flow within an ecosystem....

Recent declines in global fish stocks have raised questions regarding the sustainability of both extractive and catch-and-release fishing activities, and prompted efforts to quantify the total impact of fishing pressure. While at-vessel...

Despite the utility of data loggers for studying the fine-scale behavior and energetics of marine organisms, most studies using these tools have had relatively low sample sizes due to various factors including the logistical difficulty...

Animal movements, in particular residency or return migrations (collectively de - fined as ‘philopatry’), can shape population structure and have implications for management. This review examines the evidence for philopatry in...

The longfin mako (Isurus paucus) is a poorly studied oceanic shark taken in fisheries throughout its worldwide range in temperate and tropical waters. Satellite-linked tags were deployed to investigate the movements of 2 mature males, one...

Once abundant across all tropical and subtropical ocean basins, oceanic whitetip sharks (Carcharhinus longimanus) have experienced major population declines, resulting in the species now being listed as “Critically Endangered”...

Optimal foraging theory has been used to understand the foraging choices of animals but is rarely applied to large predatory fishes due to difficulties measuring their behavior in the wild. Great hammerhead sharks (Sphyrna mokarran)...

Animals may demonstrate area-restricted search (ARS) behaviour when encountering prey, where they turn frequently to remain in an area where the probability of finding additional prey is relatively high. We would expect optimally foraging...
