Two's company: Monozygotic twinning in the small-spotted catshark (Scyliorhinus canicula). [PDF]

J Fish Biol
Abstract Developmental abnormalities in elasmobranchs (sharks and rays) are rarely documented, with reported cases primarily involving fin or cranial deformities. Monozygotic twinning, the formation of identical twins from a single zygote, is particularly rare in these species and has been observed overwhelmingly in viviparous elasmobranchs.

Antioxidant Small-spotted Catshark Burgers

Frontiers in Marine Science, 2014
Tons of fish are rejected daily, not only on board, but also on shore during the industrial processing (INE, 2012). In order to reuse these wastes, restructured seafood products must be developed.

Pre-Hatching Ontogenetic Changes of Morphological Characters of Small-Spotted Catshark (Scyliorhinus canicula)

Fishes, 2022
The small-spotted catshark, Scyliorhinus canicula, provides an optimal model organism to include chondrichthyans in studies comparing morphology or physiology through vertebrate evolution. In particular, for investigations with ontogenetic aspects, there

Feeding habits of the small-spotted catshark Scyliorhinus Canicula (l., 1758) in the Central Mediterranean [PDF]

, 2010
The catshark Scyliorhinus canicula is a common demersal elasmobranch in the Mediterranean. It has a wide geographical and bathymetric distribution and is found primarily over sandy, muddy or gravelly bottoms.

Sexual dimorphisms in the dermal denticles of thelesser-spotted catshark, Scyliorhinus canicula (Linnaeus, 1758) [PDF]

, 2013
The dermal layers of several elasmobranch species have been shown to be sexually dimorphic. Generally, when this occurs the females have thicker dermal layers compared to those of males. This sexual dimorphism has been suggested to occur as a response to

Whole tissue imaging of cellular boundaries at sub-micron resolutions for deep learning cell segmentation: Applications in the analysis of epithelial bending of ectoderm. [PDF]

Dev Dyn
Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...

Proteomic analysis of the zone of degeneration at the mitosis-meiosis transition stage in wild-caught male catshark (Scyliorhinus canicula), correlated with an unusually high-water temperature in the English Channel. [PDF]

J Fish Biol
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

Commercial sharks under scrutiny: Baseline genetic distinctiveness supports structured populations of small-spotted catsharks in the Mediterranean Sea

Frontiers in Marine Science, 2023
The present study, based on microsatellite markers, describes a population genetic analysis of the small-spotted catshark Scyliorhinus canicula (Linnaeus, 1758), representing one of the most abundant and commonly caught cartilaginous fishes in the ...

Key drivers of at-vessel mortality in demersal sharks. [PDF]

Conserv Biol
Abstract Chondrichthyans are highly vulnerable to fisheries overexploitation, and postcapture mortality poses a significant threat to most species. Global bycatch mitigation guidelines recommend adopting hierarchical decision‐making approaches tailored to species‐specific vulnerabilities and socioeconomic and regulatory contexts.
