The dental plate on bichir pectoral fins: A unique dermal skeletal element bearing individual odontodes with tooth‐like replacement

Journal of Anatomy, Volume 249, Issue 1, Page 127-140, July 2026.
Pectoral fins of bichirs encompass the so‐called dental plates – unique dermal skeletal elements with individual odontodes identical to the oral teeth. Abstract The dermal skeleton appeared early in vertebrate evolution in the form of mineralized skin denticles composed of tooth‐like units—odontodes.

Visual Modelling to Predict Behavioural Responses of Catsharks, Skates, and Plaice to Artificial Light for Use in Bycatch Reduction

Fisheries Management and Ecology, Volume 33, Issue 3, Page 463-478, June 2026.
ABSTRACT Light can be used to deter bycatch from fishing nets, but few studies have aimed to quantify how species view and respond to light. Here, we used visual models to predict how target (plaice Pleuronectes platessa) and bycatch (small‐spotted catshark Scyliorhinus canicular and undersized skates, Raja spp) species, captured in mixed demersal ...

Biofluorescence in Catsharks (Scyliorhinidae): Fundamental Description and Relevance for Elasmobranch Visual Ecology [PDF]

Scientific Reports, 2016
AbstractBiofluorescence has recently been found to be widespread in marine fishes, including sharks. Catsharks, such as the Swell Shark (Cephaloscyllium ventriosum) from the eastern Pacific and the Chain Catshark (Scyliorhinus retifer) from the western Atlantic, are known to exhibit bright green fluorescence.

The Shark Basal Hypothalamus: Molecular Prosomeric Subdivisions and Evolutionary Trends

Frontiers in Neuroanatomy, 2018
The hypothalamus is a key integrative center of the vertebrate brain. To better understand its ancestral morphological organization and evolution, we previously analyzed the segmental organization of alar subdivisions in the catshark Scyliorhinus ...

Community–environment interactions explain octopus-catshark spatial overlap [PDF]

ICES Journal of Marine Science, 2016
AbstractThe octopus Eledone cirrhosa and the catshark Scyliorhinus canicula present the same feeding habits and distributional preferences in the Mediterranean Sea. We explore patterns of spatial overlap between these species to address coexistence and infer possible competition from spatial patterns in the western Mediterranean Sea.

Apristurus breviventralis, Shortbelly Catshark [PDF]

, 2017
The Shortbelly Catshark (Apristurus breviventralis) is known from only nine specimens from the Gulf of Aden around the Socotra Islands, Yemen. It occurs at 1,000-1,120 m depth, reaches at least 48.5 cm total length, but its biology is virtually unknown.

The fin-to-limb transition as the re-organization of a Turing pattern

Nature Communications, 2016
Mouse digit patterning is controlled by a Turing network of Bmp, Sox9, and Wnt. Here, Onimaru et al. show that fin patterning in the catshark, Scyliorhinus canicula, is controlled by the same network with a different spatial organization; thus, the ...

Resilience to Cardiac Aging in Greenland Shark Somniosus microcephalus

Aging Cell, Volume 25, Issue 5, May 2026.
Greenland shark Somniosus microcephalus shows severe cardiac aging such as fibrosis, lipofuscin buildup, mitochondrial damage, and oxidative stress, unseen in comparison species Etmopterus spinax and Nothobranchius furzeri, yet remain healthy. S. microcephalus resilience suggests unique mechanisms that preserve heart function for centuries, offering ...
