Regionalization of the shark hindbrain: a survey of an ancestral organization

Frontiers in Neuroanatomy, 2011
Cartilaginous fishes (chondrichthyans) represent an ancient radiation of vertebrates currently considered the sister group of the group of gnathostomes with a bony skeleton that gave rise to land vertebrates. This out-group position makes chondrichthyans

The complete mitochondrial genome and phylogenetic position of the leopard catshark, Poroderma pantherinum

Mitochondrial DNA. Part B. Resources, 2018
We present the first mitochondrial genome of a South African endemic catshark, Poroderma pantherinum. The complete mitogenome is 16,686 bp in length, comprising 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and one non-coding control region ...

Oviparous elasmobranch development inside the egg case in 7 key stages. [PDF]

PLoS ONE, 2018
Embryological stages of oviparous elasmobranch during development can be difficult to identify, requiring magnification and/or fixation of an anaesthetized embryo.

Divergent Expression of SPARC, SPARC-L, and SCPP Genes During Jawed Vertebrate Cartilage Mineralization

Frontiers in Genetics, 2021
While cartilage is an ancient tissue found both in protostomes and deuterostomes, its mineralization evolved more recently, within the vertebrate lineage.

Nodular Lesions in the Pyloric Caeca of Sardinella aurita (Teleostei) Associated With the Cestode Anthobothrium sp. 1 Larvae (Platyhelminthes: Eucestoda) Off Tunisia, Mediterranean Sea

Journal of Fish Diseases, EarlyView.
ABSTRACT Examination of round sardinella Sardinella aurita Valenciennes, 1847 (Clupeidae) from the Gulf of Tunis (Tunisia) revealed the first local and Mediterranean record of Anthobothrium sp. 1 sensu Jensen & Bullard, 2010 (Tetraphyllidea incertae sedis, Anthobothrium).

Reproductive biology of lesser spotted dogfish Scyliorhinus canicula (L., 1758) in the Cantabrian Sea

Scientia Marina, 1998
This paper examines sexual maturity of the female lesser spotted dogfish Scyliorhinus canicula (L., 1758) in the Cantabrian Sea (north of Spain). Analyses made using data collected from commercial trawlers during 1994 and 1995 showed that females reach ...

Marine‐Derived Type I Collagen From Scyliorhinus canicula : Extraction, Characterization, and Biomedical Applications

Journal of Applied Polymer Science, Volume 143, Issue 43, November 15, 2026.
Marine‐derived type I collagen is extracted from Scyliorhinus canicula skin and characterized by physicochemical and morphological analyses. The collagen exhibits excellent biocompatibility, promotes wound healing, reduces inflammatory mediators, and inhibits melanogenesis.

Elasmobranch Mark–Recapture Experiment off the Balearic Islands: Insight into Scyliorhinus canicula Growth, Mobility, and Population Size

Fishes
Despite the high diversity of elasmobranch fishes in the Balearic Islands, knowledge of their biology and population dynamics is still scarce. A recent mark-and-recapture experiment off the Balearic Islands tagged 3738 individuals of 23 shark and batoid ...

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

Metal accumulation and metallothionein induction in the spotted dogfish Scyliorhinus canicula [PDF]

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2009
Recent studies indicate that elasmobranch fish respond differently to metal exposure than marine teleosts. Accumulation rates can be high, which despite the fact that normal background levels for metals in the marine environment are low, is worrying due to the long life span and late fecundity of most shark.
