Extending records of albinism and skin disorders in <span>American</span> cownose rays to southeastern <span>Brazil</span> Open
Albinism is a genetic condition expressed as a lack of integumentary and retinal melanin. Although documented across many vertebrate species, albinism and other skin disorders are rarely observed in elasmobranchs (sharks and rays). The pre…

Urban Living Affects the Nutrition of Sharks Open
It is common to see some wild animals in the city, like squirrels and raccoons, but have you ever thought about sharks in the city? While you will not see a shark hanging out on the streets of downtown, you may see one swimming along the s…

Female wound records suggest mating periods for the Caribbean reef shark at an insular marine protected area from the Equatorial Atlantic Ocean Open
Despite being one of the most abundant, economically significant, reef‐associated shark species, little is known about the reproductive aspects of the Caribbean reef shark ( Carcharhinus perezi ). In the present study the authors report th…

SIA‐BRA: A database of animal stable carbon and nitrogen isotope ratios of Brazil Open
Motivation SIA‐BRA is a data set that compiles stable carbon (C) and nitrogen (N) isotope ratios of terrestrial and aquatic animals sampled in Brazilian biomes and coastal marine areas. Stable isotope ratios are helpful in animal ecology f…

Ecomorphological, space, and mineral relations of dermal denticles in angular angel shark (<span><i>Squatina guggenheim</i></span>) Open
Shark skin is predominantly specialized for swimming and protection, with the dermal denticle being the main structure associated with these abilities. The dermal denticle is a mineral structure with a unique morphology for each species, w…

NEW RECORDS AND PRELIMINARY REPRODUCTIVE ASPECTS OF ELASMOBRANCHS OF THE TRINDADE-MARTIN VAZ INSULAR COMPLEX Open
Here we presented records of elasmobranchs obtained during a longline pelagic fishing monitoring around the Trindade-Martin Vaz insular complex, including one new record. New information on the reproductive aspects of the blue shark (Prion…

CAPTURE AND HANDLING STRESS IN INCIDENTALLY CAPTURED RAYS FROM SMALL-SCALE FISHING: A PHYSIOLOGICAL APPROACH Open
Incidental capture is the most common threat to rays worldwide, by both artisanal and industrial fishing. To better understand this threat, we evaluated the capture and handling stress in three incidentally captured benthopelagic ray speci…

Effects of biological traits on capture‐induced parturition in a freshwater stingray and perspectives for species management Open
Elasmobranchs are particularly vulnerable to overexploitation and population depletion, especially due to their life‐history traits, such as low reproductive output and slow growth. Given that capture‐induced parturition (abortion or prema…

Microstructural morphology of dermal and oral denticles of the sharpnose sevengill shark <span><i>Heptranchias perlo</i></span> (Elasmobranchii: Hexanchidae), a deep‐water species Open
The dermal denticles are among the unique morphological adaptations of sharks, which have been acquired throughout their long evolutionary process of more than 400 million years. Species‐specific morphological characteristics of these stru…

REPORT OF INJURIES IN BATOIDS CAUGHT IN SMALL-SCALE FISHERIES: IMPLICATIONS FOR MANAGEMENT PLANS Open
Despite of the ecological importance of several batoids caught as bycatch, little attention is given to the individual resilience in risk assessments. The report of physical condition is imperative for a realistic understanding of the impa…

Use of a nursery area by cownose rays (Rhinopteridae) in southeastern Brazil Open
Using non-lethal methods for data collection of individuals and participatory monitoring by fishermen, we provide the first empirical evidence of the use of a nursery area by neonate and young-of-the-year cownose rays Rhinoptera bonasus an…

Microscopic aspects of electrosensory system on the partially euryhaline lesser guitarfish Open
The electrosensory system on elasmobranchs consists of subcutaneous electroreceptor organs known as ampullae of Lorenzini. The present study investigated the ampullae of Lorenzini morphology of the lesser guitarfish Zapteryx brevirostris, …

Molecular evidence supporting the expansion of the geographical distribution of the Brazilian cownose ray Rhinoptera brasiliensis (Myliobatiformes: Rhinopteridae) in the western Atlantic Open
The genus Rhinoptera is composed of eight species widely distributed in tropical, subtropical and temperate coastal waters, which inhabit bays, estuaries and river mouths. Cownose ray Rhinoptera bonasus has been reported to inhabit the Wes…

A preliminary investigation into the morphology of oral papillae and denticles of blue sharks (<i>Prionace glauca</i>) with inferences about its functional significance across life stages Open
Sensory organs in elasmobranchs (sharks, skates, rays) detect and respond to a different set of biotic and/or abiotic stimuli, through sight, smell, taste, hearing, mechanoreception and electroreception. Although gustation is crucial for s…
