The immunoglobulins of cartilaginous fishes [PDF]

Developmental and Comparative Immunology, 2021
Cartilaginous fishes, comprising the chimeras, sharks, skates, and rays, split from the common ancestor with other jawed vertebrates approx. 450 million years ago. Being the oldest extant taxonomic group to possess an immunoglobulin (Ig)-based adaptive immune system, examination of this group has taught us much about the evolution of adaptive immunity,

Morphology and evolutionary significance of phosphatic otoliths within the inner ears of cartilaginous fishes (Chondrichthyes) [PDF]

BMC Evolutionary Biology, 2019
Background Chondrichthyans represent a monophyletic group of crown group gnathostomes and are central to our understanding of vertebrate evolution. Like all vertebrates, cartilaginous fishes evolved concretions of material within their inner ears to aid ...

Adaptive loss of shortwave-sensitive opsins during cartilaginous fish evolution [PDF]

Nature Communications
Cartilaginous fishes (e.g., sharks, rays, and skates) cannot see blue or violet light, potentially because they lack the shortwave-sensitive cone opsin gene (sws).

Cartilaginous fish and mammalian connectin evolved independently from an ancestral bony fish-like structure [PDF]

Scientific Reports
Connectin, also known as titin, is the largest protein that connects the Z-line to M-line of the sarcomere, functioning as a molecular spring to regulate muscle extensibility.

Single-cell RNA sequencing illuminates the ontogeny, conservation and diversification of cartilaginous and bony fish lymphocytes [PDF]

Nature Communications
Elucidating cellular architecture and cell-type evolution across species is central to understanding immune system function and susceptibility to disease.

Diversity and Evolution of Mineralized Skeletal Tissues in Chondrichthyans

Frontiers in Ecology and Evolution, 2021
The diversity of skeletal tissues in extant vertebrates includes mineralized and unmineralized structures made of bone, cartilage, or tissues of intermediate nature. This variability, together with the diverse nature of skeletal tissues in fossil species

Updated checklist of Azores Chondrichthyes (Vertebrata: Gnathostomata) [PDF]

Biodiversity Data Journal, 2021
Several lists of marine fish from the Azores were published in the past. Most of those publications are difficult to access on line and several were not published in peer reviewed journals.This checklist updates all the chondrichthyan records for the ...

Revealing less derived nature of cartilaginous fish genomes with their evolutionary time scale inferred with nuclear genes. [PDF]

PLoS ONE, 2013
Cartilaginous fishes, divided into Holocephali (chimaeras) and Elasmoblanchii (sharks, rays and skates), occupy a key phylogenetic position among extant vertebrates in reconstructing their evolutionary processes. Their accurate evolutionary time scale is
