Environmental controls of species diversity represent a central research focus in
evolutionary biology. In the marine realm, sharks are widely distributed, occupying mainly …

The evolution of gigantism in extinct otodontid sharks was paralleled by a series of drastic
modifications in their dentition including widening of the crowns, loss of lateral cusplets, and …

Devonian ctenacanth chondrichthyans reached body sizes similar to modern great white
sharks and therefore might have been apex predators of the Devonian seas. However, very …

Sharks are threatened by several human activities that impact their distribution and
abundance. A great proportion of shark captures happen as incidental capture (bycatch) by …

Kinematic and behavioral studies of feeding performance in large, pelagic sharks have
historically been hindered by logistical limitations including a lack of access to specimens …

Simple Summary Labial cartilages (LCs) are structures along the jaws of many sharks that
are known, in some species, to enable or support suction, but there are many different …

Feeding performance represents a suite of kinematic events and behaviors that achieve the
ecologically relevant task of nutrient acquisition. Quantitative accounts of feeding kinematics …

In marine systems, behaviorally-mediated indirect interactions between prey,
mesopredators, and higher trophic-level, large predators are less commonly investigated …

Many studies on shark swimming have examined kinematic variables along straight tracks
or under controlled flow speeds in flumes, but there is less known about unsteady swimming …

The grey nurse, ragged-tooth or sand tiger shark Carcharias taurus Rafinesque, 1810
occurs in seven genetically distinct populations in subtropical and warm temperate oceans …
