European Shark Fisheries: A Preliminary Investigation into Fisheries, Conversion Factors, Trade Products, Markets and Management Measures [PDF]
, 2007 Recommends new regulations to prevent shark finning -- an illegal practice in which a shark's fins are removed and its carcass dumped at sea -- and stresses the urgent need for effective shark conservation ...

Ultimate Eocene (Priabonian) chondrichthyans (Holocephali, Elasmobranchii) of Antarctica [PDF]
Journal of Vertebrate Paleontology, 2016 The Eocene La Meseta Formation on Seymour Island, Antarctic Peninsula, is known for its remarkable wealth of fossil remains of chondrichthyans and teleosts. Chondrichthyans seemingly were dominant elements in the Antarctic Paleogene fish fauna, but decreased in abundance from middle to late Eocene, during which time remains of bony fishes increase ...

Early evolution of the gular musculature and its innervation in ray‐finned fishes
The Anatomical Record, EarlyView.Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating

Sharks, bony fishes and endodental borings from the Miocene Montpelier Formation (White Limestone Group) of Jamaica [PDF]
, 2004 Bulk samples of Miocene carbonate sediments (deep-water chalks and shallow-water-derived calcarenites) from the Montpelier Formation (White Limestone Group) in Duncans Quarry, Jamaica, have yielded a small, but diverse, fauna of disassociated fish ...

Biological Reviews, EarlyView.ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

The whale shark genome reveals patterns of vertebrate gene family evolution
eLife, 2021 Chondrichthyes (cartilaginous fishes) are fundamental for understanding vertebrate evolution, yet their genomes are understudied. We report long-read sequencing of the whale shark genome to generate the best gapless chondrichthyan genome assembly yet ...

A nursery site of the Alaska skate (Bathyraja parmifera) in the eastern Bering Sea [PDF]
, 2008 A nursery site for the Alaska skate (Bathyraja parmifera) was sampled seasonally from June 2004 to July 2005. At the small nursery site (~2 km2), located in a highly productive area near the shelf-slope interface at the head of Bering Canyon in the ...
