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

Journal of Anatomy, EarlyView.
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.

Early life sensory ability—ventilatory responses of thornback ray embryos (Raja clavata) to predator-type electric fields [PDF]

, 2015
Predator avoidance is fundamental for survival and it can be particularly challenging for prey animals if physical movement away from a predatory threat is restricted. Many sharks and rays begin life within an egg capsule that is attached to the sea bed.

Genetic Diversity and Population Structure of Squalus cf. mitsukurii (Chondrichthyes: Squalidae) Revealed by ddRAD Sequencing

Animal Genetics, Volume 57, Issue 2, April 2026.
ABSTRACT Assessing genetic structure across ocean basins is essential to understand connectivity and guide conservation in data‐deficient open‐water sharks. In this study, we examined the population genomics of Squalus cf. mitsukurii by analyzing tissue samples collected from two distant regions: California, USA (Pacific Ocean) and Pernambuco, Brazil ...

In the quest of the optimal chondrichthyan for the development of collagen sponges for articular cartilage

Journal of Science: Advanced Materials and Devices, 2021
The limited capability of articular cartilage to self-repair renders its regeneration a formidable challenge. In the quest of the optimal material for cartilage scaffold fabrication, the use of collagen type II has been advocated, but its optimal source ...
