A novel field method to distinguish between cryptic carcharhinid sharks, Australian blacktip shark Carcharhinus tilstoni and common blacktip shark C. limbatus, despite the presence of hybrids

, 2017
Multivariate and machine-learning methods were used to develop field identification techniques for two species of cryptic blacktip shark. From 112 specimens, precaudal vertebrae (PCV) counts and molecular analysis identified 95 Australian blacktip sharks

Speed‐dependent locomotor patterns during steady swimming in a demersal shark

Journal of Fish Biology, Volume 107, Issue 2, Page 394-405, August 2025.
Abstract Swimming ability is critical for navigating complex benthic habitats, yet the biomechanical strategies demersal sharks employ to modulate body and fin movements across varying speeds remain largely unexplored. This study examines speed‐dependent kinematic patterns in the small‐spotted catshark (Scyliorhinus canicula), a benthic species with ...

Multiple species of Phoreiobothrium from the blacktip shark, Carcharhinus limbatus, in the Gulf of Mexico [PDF]

, 2008
During a survey of the adult tapeworm fauna of sharks from the Gulf of Mexico, the blacktip shark, Carcharhinus limbatus (Müller and Henle, 1839), was found to host cestodes in the genus Phoreiobothrium.

How Fragmented Is eDNA? A Case Study on Shark DNA in Tropical Reef Seawater

Environmental DNA, Volume 7, Issue 4, July–August 2025.
This study quantified mitochondrial eDNA fragment lengths in offshore tropical seawater using qPCR assays targeting amplicons from 119 to 15,727 bp in tiger shark (Galeocerdo cuvier). Copy numbers steeply declined with increasing fragment size, with successful amplification up to 1518 bp and a calculated mean undamaged fragment size of 256 bp.

Scaling of bite force corresponds with ontogenetic niche shifts in coastal elasmobranchs

Frontiers in Marine Science
IntroductionPredators, such as sharks, play important ecological roles in coastal ecosystems when abundant and these roles change over ontogeny. However, these shifts in ecological role are often not evaluated in light of feeding performance.

Defining Sex-Specific Habitat Suitability for a Northern Gulf of Mexico Shark Assemblage

Frontiers in Marine Science, 2020
Understanding the factors that influence species’ distributions is crucial for implementing effective management and conservation practices, yet difficult for highly vagile species like sharks.

Unseen Experts of the Sea: Fishers' Local Ecological Knowledge Reveals Elasmobranch Hotspot Decline Around Curaçao, Dutch Caribbean

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 6, June 2025.
ABSTRACT Fishing pressure is the primary threat to coastal elasmobranch populations, and understanding its impact requires long‐term regional data—often lacking in complex, small‐scale fishery settings. This is the case for Curaçao, a southern Dutch Caribbean island with an unmonitored artisanal fishery where, according to anecdotes, elasmobranchs have

Spatial patterns of the epipelagic species caught incidentally in the tuna fishery on floating objects, in the eastern Pacific Ocean

Ciencias Marinas, 2001
The spatial pattern of the fauna associated with floating objects in the eastern tropical Pacific (ETP) was analyzed. Different presence indexes for the groups of species caught incidentally in log sets were estimated, using information from the Inter ...

Nursery Resource Use Dynamics in Great Hammerheads (Sphyrna mokarran) Across Ontogeny

Ecology and Evolution, Volume 15, Issue 6, June 2025.
The ecological trade‐offs required by nursery dependence are poorly understood. Using multi‐tissue stable isotope analysis, this research provides evidence of constrained resource use in juvenile great hammerheads (Sphyrna mokarran) associated with year‐round dependence on the Biscayne Bay nursery during their first two years of life.
