Residencia del tiburón punta blanca de arrecife, Triaenodon obesus, (Carcharhiniformes: Carcharhinidae) en las bahías Chatham y Wafer del Parque Nacional Isla del Coco, Costa Rica [PDF]

open access: yesRevista de Biología Tropical, 2020
Introducción: El tiburón punta blanca (Triaenodon obesus) es una especie de arrecife de aguas tropicales, no migratoria, que ha demostrado no tener una alta conectividad costera, como la observada para otras especies de tiburón, sin embargo posee la distribución más amplia de todas las demás especies de tiburón de arrecife del Indo-Pacífico. T. obesus,

Corrigendum: Use of Synthetic Salmon GnRH and Domperidone (Ovaprim®) in Sharks: Preparation for ex situ Conservation

open access: yesFrontiers in Marine Science, 2021
In the original article, there was an error. We have used the whitetip reef shark (Triaenodon obesus) for this study but wrote the species name incorrectly as the Oceanic whitetip shark (Carcharhinus longimanus).

Defining ecological roles of sharks on coral reefs. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT Sharks have often been perceived to play a critical role in the dynamics of coral reef ecosystems globally. Yet, there is relatively little evidence to support this idea across all but a limited set of species and contexts. Research on the roles and importance of reef sharks has been complicated by logistical challenges in collecting data on ...

Summarising 40 years of gastric lavage studies to evaluate efficiency and survival in sharks and rays. [PDF]

open access: yesJ Fish Biol
Abstract Traditionally, lethal stomach dissection has been used to study the diets of sharks and rays, but conservation and animal welfare concerns necessitate non‐lethal alternatives, such as gastric lavage (stomach or gut flushing). In this study, we summarised gastric lavage studies on elasmobranchs to identify which species/groups it has been ...

Abundance, demography and population structure of the grey reef shark (Carcharhinus amblyrhynchos) and the white tip reef shark (Triaenodon obesus) (Fam. Charcharhinidae) [PDF]

open access: yes, 2006
Reef sharks (fam. Carcharhinidae) are high-order predators, found throughout the Indo- Pacific. I examined the abundance, growth, reproduction and demography of two species of reef carcharhinid; the grey reef shark (Carcharhinus amblyrhynchos) and the whitetip reef shark (Triaenodon obesus), and investigated the genetic stock structure of T.

The Phenomenon of Piebaldism in Sharks: A Review of Global Sightings and Patterns. [PDF]

open access: yesEcol Evol
Chromatic disorders like piebaldism—a rare form of leucism causing partial pigment loss—have been documented in 25 wild shark cases across 17 species and 11 families, with varying anatomical distribution. This study compiles published and unpublished records to better understand the taxonomic and geographical spread of piebaldism and its potential ...

Using citizen science photographs to identify reproductive events in an oviparous elasmobranch. [PDF]

open access: yesJ Fish Biol
Abstract Identifying critical habitats is important for the effective management of vulnerable species. Critical habitats, such as mating or nursery grounds, support populations during key life stages and help to maximise reproductive output and population growth. In elasmobranchs, mating often happens over a defined season, suggesting sites associated
