Tooth mineralization and histology patterns in extinct and extant snaggletooth sharks, Hemipristis (Carcharhiniformes, Hemigaleidae)-Evolutionary significance or ecological adaptation? [PDF]

PLoS ONE, 2018
Shark jaws exhibit teeth that are arranged into distinct series and files and display great diversities in shapes and structures, which not only is related to their function (grasping, cutting, crushing) during feeding, but also bear a strong ...

Retention Bans Are Beneficial but Insufficient to Stop Shark Overfishing

Fish and Fisheries, Volume 26, Issue 3, Page 473-487, May 2025.
ABSTRACT Sharks are among the most threatened groups of exploited fishes, comprising common bycatch across many fisheries. Management efforts intended to safeguard threatened species have increasingly focused on retention bans to reduce bycatch mortality. However, the population effects of such measures remain unevaluated across species.

Dental crown morphological variation and heterodonty in carcharhiniform sharks

The Anatomical Record
Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce.

Predicting time‐at‐depth weighted biodiversity patterns for sharks of the North Pacific

Ecography, Volume 2025, Issue 3, March 2025.
Depth is a fundamental and universal driver of ocean biogeography but it is unclear how the biodiversity patterns of larger, more mobile organisms change as a function of depth. Here, we developed a predictive biogeography model to explore how information of mobile species' depth preferences influence biodiversity patterns.

Design and Validation of an Open–Close Device for Integrated Environmental DNA Sampling Detects A Depth Gradient in Indian Ocean Deep‐Sea Fish Assemblages

Ecology and Evolution, Volume 15, Issue 2, February 2025.
The goal of this study was to leverage existing survey technology to design and test an eDNA sampler that captures an integrated eDNA sample over the length of a deep‐water transect. We provide a biological interpretation of the resulting data, demonstrating the usefulness of such technology to understand the ocean environments, using fish species as ...

PROBLEMATIC IDENTITY OF THE SMALLEYE HAMMERHEAD (CARCHARHINIFORMES: SPHYRNA) OCCURRING IN COLOMBIA

Bulletin of Marine and Coastal Research, 2016
The presence of Sphyrna tudes in Colombian waters is supported by a 506 mm total length male collected in the southernmost corner of the Caribbean Sea, the mouth of Atrato river. A short discussion on the confusing taxonomic and nomenclatural history of the smalleye hammerhead is included.

Mitochondrial DNA patterns describe the evolutionary history of the bonnethead shark Sphyrna tiburo (Linneus 1758) complex in the western Atlantic Ocean

Journal of Fish Biology, Volume 106, Issue 2, Page 403-419, February 2025.
Abstract The apparent lack of physical barriers in the marine realm has created the conception that many groups have a constant gene flow. However, changes in ocean circulation patterns, glacial cycles, temperature, and salinity gradients are responsible for vicariant events in many fish species, including sharks.
