Morphological Diversity of Neurocrania in Sharks (Chondrichthyes: Elasmobranchii) and Its Ecological and Evolutionary Implications [PDF]
Sharks occupy a wide range of ecological niches and lifestyle strategies attributed to their complex sensory system housed in their neurocranium. However, the diversity of neurocranial morphology in sharks and how the diversity may be related to their ...

What is known about cookiecutter shark (Isistius spp.) interactions with cetaceans in Cape Verde seas? [PDF]
In the North Atlantic, the waters surrounding the Cape Verde Islands are a "potential hot spot" for cookiecutter shark Isistius spp. interactions with cetaceans. These occurrences were recently identified by the improved efforts of researchers to document cetacean strandings in the Cape Verde archipelago, as well as by the photo identification efforts ...

Extinction risk and conservation of the world\u27s sharks and rays [PDF]
The rapid expansion of human activities threatens ocean-wide biodiversity. Numerous marine animal populations have declined, yet it remains unclear whether these trends are symptomatic of a chronic accumulation of global marine extinction risk.

Body Forms in Sharks (Chondrichthyes: Elasmobranchii), and Their Functional, Ecological, and Evolutionary Implications [PDF]
Sharks are among the oldest vertebrate lineages in which their success has been attributed to their diversity in body shape and locomotor design. In this study, I investigated the diversity of body forms in extant sharks using landmark-based geometric ...
