Narrownose smoothhound (Mustelus schmitti) shark liver: From a residue to a high added value biocompounds

Food Chemistry Advances
The exploration of fishery wastes for the extraction of value-added biocompounds has become a topic of current interest. The aim of this work was to promote a circular economy model by obtaining oil by enzymatic hydrolysis from Mustelus schmitti livers ...

Conservación de secciones corporales y órganos de gatuzo, mustelus schmitti (Pisces, chondrichthyes), por inyección de silicona a temperatura ambiente para ser utilizados en el aprendizaje de anatomía comparada [PDF]

International Journal of Morphology, 2018
Comparative Anatomy deals with the study of the ontogenetic and phylogenetic changes of the vertebrates, requiring complementing the theoretical aspects with the observation of structures in specimens belonging to different taxonomic groups.

Heavy Metal Bioaccumulation by Cestode Parasites of Mustelus Schmitti (Chondrichthyes: Carcharhiniformes), from the Bahía Blanca Estuary, Argentina [PDF]

, 2019
The environment of the Bahía Blanca estuary is considered a hot spot in terms of pollution. Bioindicators should have the ability to react relatively fast to certain pollutants and environmental disturbances.

Distribution patterns and interactions of cestodes in the spiral intestine of the narrownose smooth-hound shark, Mustelus schmitti Springer, 1939 (Chondrichthyes, Carcharhiniformes) [PDF]

Acta Parasitologica, 2006
The distribution patterns and the cestode species interactions within the spiral intestine of 20 specimens of Mustelus schmitti from coastal waters off Mar del Plata, Argentina were studied. Six cestode species were found: Tetraphyllideans Calliobothrium

Slippery and Smooth Shark Skin: How Mucus Transforms Surface Texture. [PDF]

J Morphol
Shark surfaces consist of denticles and a mucus layer, yet mucus is an understudied aspect of shark surfaces. Using gel‐based surface profilometry to visualize and quantify surface texture changes, we found that mucus covered denticles on the dorsal fin tip and tip of the tail's trailing edge.

Shearing Tooth Morphology May Allow Sharks to Access Higher Trophic Levels at Smaller Sizes. [PDF]

Ecol Evol
Predator morphology imposes limitations on prey selection due to biomechanical constraints, making some prey functionally inaccessible and thereby constraining predator trophic niches. We assessed how two key components of trophic morphology—tooth shape and body size—affect prey selectivity and trophic niche in two sympatric sharks with contrasting ...

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.

First recorded case of leucism in the velvet belly lantern shark Etmopterus spinax (Squaliformes: Etmopteridae)

Journal of Applied Ichthyology, Volume 38, Issue 4, Page 455-461, July 2022., 2022
Abstract The capture of a female specimen of the velvet belly lantern shark Etmopterus spinax with abnormal skin coloration is reported. The specimen was captured off northern Spain (Bay of Biscay, North‐eastern Atlantic) in 2021 by bottom trawling. The lack of dermal melanophores combined with a normal retinal pigmentation, lead us to considerate the ...
