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

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

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.

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 [PDF]

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.

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 ...

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 ...

Ontogenetic trophic segregation between two threatened smooth-hound sharks in the Central Mediterranean Sea. [PDF]

Sci Rep, 2020
Elasmobranchs are among the species most threatened by overfishing and a large body of evidence reports their decline around the world. As they are large predators occupying the highest levels of marine food webs, their removal can alter the trophic ...

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]

Sharks, 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 characteristics.

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.

Two thirds of species in a global shark fin trade hub are threatened with extinction: Conservation potential of international trade regulations for coastal sharks

Conservation Letters, Volume 15, Issue 5, September/October 2022., 2022
Abstract One third of chondrichthyan species (sharks, rays, and chimeras) are threatened with extinction, mainly due to unsustainable fishing. Large accessible international markets for meat and luxury products like dried fins can help drive overfishing by encouraging targeted capture or retention of high‐value export species.
