Rapid DNA/eDNA-Based ID Tools for Improved Chondrichthyan Monitoring and Management. [PDF]

Mol Ecol Resour
ABSTRACT Rapid DNA/eDNA‐based ID tools, which detect specific genetic patterns without requiring sequencing, are essential for biodiversity and wildlife trade monitoring, particularly for species of conservation concern. However, the practical application of these methods remains limited by the availability of standardised protocols, accessibility of ...

The denticle surface of thresher shark tails: Three‐dimensional structure and comparison to other pelagic species

Journal of Morphology, 2020
AbstractShark skin denticles (scales) are diverse in morphology both among species and across the body of single individuals, although the function of this diversity is poorly understood. The extremely elongate and highly flexible tail of thresher sharks provides an opportunity to characterize gradients in denticle surface characteristics along the ...

Cleaner wrasse forage on ectoparasitic digeneans (phylum Platyhelminthes) that infect pelagic thresher sharks (Alopias pelagicus) [PDF]

Marine Biodiversity, 2014
The cleaning system is a classic model for cooperative behaviour among species in which cleaner fish or shrimps remove parasites and/or dead tissue from clients that pose at stations to solicit services from them (Cote 2000). Sharks, including pelagic thresher sharks, host a variety of ectoparasites that may affect their health and fitness (Oliver et ...

Effects of protection on large-bodied reef fishes in the western Indian Ocean. [PDF]

Conserv Biol
Abstract Predatory and large‐bodied coral reef fishes have fundamental roles in the functioning and biodiversity of coral reef ecosystems, but their populations are declining, largely due to overexploitation in fisheries. These fishes include sharks, groupers, Humphead wrasse (Cheilinus undulatus), and Green Humphead parrotfish (Bolbometopon muricatum).

Shark conservation hindered by lack of habitat protection

Global Ecology and Conservation, 2020
Many of the world’s shark populations are in decline, indicating the need for improved conservation and management. Well managed and appropriately located marine parks and marine protected areas (MPAs) have potential to enhance shark conservation by ...

Growth estimates of pelagic thresher shark (Alopias pelagicus Nakamura, 1935) in the Indian Ocean Southern Java waters

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Alopias pelagicus were highly migratory species, oceanic and almost always found in tropical and temperate seas. This species was particularly vulnerable to exploitation of both targets and side catches. Research was conducted in May 2015 to November 2016 at the landing site of the Cilacap Fishing Port.

Thresher sharks use tail-slaps as a hunting strategy.

PLoS ONE, 2013
The hunting strategies of pelagic thresher sharks (Alopias pelagicus) were investigated at Pescador Island in the Philippines. It has long been suspected that thresher sharks hunt with their scythe-like tails but the kinematics associated with the ...

Feeding behavior and trophic interaction of three shark species in the Galapagos Marine Reserve [PDF]

PeerJ, 2018
There is great concern about the future of sharks in Ecuador because of the lack of biological knowledge of most species that inhabit the region. This paper analyzes the feeding behavior of the pelagic thresher shark (Alopias pelagicus), the blue shark ...
