Multiple paternity and hybridization in two smooth-hound sharks. [PDF]

Sci Rep, 2015
Multiple paternity appears to be a common trait of elasmobranch mating systems, with its occurrence likely driven by convenience, due to females seeking to minimize the stress of male harassment.

Classification of sharks in the Egyptian Mediterranean waters using morphological and DNA barcoding approaches. [PDF]

PLoS ONE, 2011
The identification of species constitutes the first basic step in phylogenetic studies, biodiversity monitoring and conservation. DNA barcoding, i.e. the sequencing of a short standardized region of DNA, has been proposed as a new tool for animal species

Trophic Partitioning among Three Mesopredatory Shark Species Inhabiting the Northwestern Adriatic Sea

Diversity, 2023
While the general diet of Mediterranean elasmobranchs has been widely studied, little is known about food partitioning and competition among sympatric species, despite these being important forces structuring marine communities. Using stomach content and

Predictive habitat suitability models to aid conservation of elasmobranch diversity in the central Mediterranean Sea. [PDF]

Sci Rep, 2015
Commercial fisheries have dramatically impacted elasmobranch populations worldwide. With high capture and bycatch rates, the abundance of many species is rapidly declining and around a quarter of the world’s sharks and rays are threatened with extinction.

Gastrointestinal Helminthofauna of Mediterranean Elasmobranchs [PDF]

Journal of Marine Science and Engineering
Elasmobranchs (Chondrichthyes, Elasmobranchii) are exposed to a variety of gastrointestinal parasites acquired through the ingestion of infected prey. An increasing amount of evidence suggests the usefulness of parasitological information to elucidate ...

Influence of ecological traits on spatio-temporal dynamics of an elasmobranch community in a heavily exploited basin. [PDF]

Sci Rep, 2023
Elasmobranchs, which include sharks and batoids, play critical roles in maintaining the integrity and stability of marine food webs. However, these cartilaginous fish are among the most threatened vertebrate lineages due to their widespread depletion ...

First fossil record of Mustelus aff. punctulatus Risso, 1826: new evidence for a smooth-hound shark population in the Late Miocene North Sea Basin

Geologica Belgica, 2022
Mustelus is a problematic genus in palaeoichthyology. Due to the scarcity of fossil teeth, relative homogeneity in tooth morphology and the lack of published extant dentitions, the early history of smooth-hound sharks remains poorly understood. Recently, two teeth were collected in the Tortonian Deurne Member (Diest Formation) near Antwerp (Belgium ...

Decoding fishery survival rates and use of space of smooth hounds (Mustelus mustelus and Mustelus punctulatus) and spiny dogfish (Squalus acanthias) with a sentinel acoustic array in the Northern Adriatic Sea [PDF]

openSharks, rays and skates have been declining worldwide, particularly in heavily exploited basins such as the Mediterranean Sea. Overfishing and bycatch are the major reasons, taking advantage of these animals’ innately sensitive life-history ...

Sharks Do Not Always Grow Slowly: Tagging Data Reveal a Different Pattern of Growth, Longevity and Maturity for Threatened Smooth-Hounds in the Central Mediterranean Sea

Journal of Marine Science and Engineering, 2022
Elasmobranchs are among the marine species more threatened by overfishing. Their conservation is often impaired by the lack of knowledge of species’ life history traits.

New Molecular Tools for the Identification of 2 Endangered Smooth-Hound Sharks, Mustelus mustelus and Mustelus punctulatus [PDF]

Journal of Heredity, 2014
The smooth-hounds represent a significant proportion of the elasmobranch catch in the Adriatic basin of the Mediterranean Sea, where the common (Mustelus mustelus) and blackspotted (Mustelus punctulatus) smooth-hounds co-occur. The 2 species share several morphological and morphometric characters that lead to frequent misidentification.
