Remoras are a highly specialised group of fishes known to associate with a range of marine
megafauna, including elasmobranchs, cetaceans and marine reptiles. Remoras appear to …

Looking to nature for inspiration has led to many diverse technological advances. The spiral
valve intestine of sharks has provided the opportunity to observe the efficiency of different …

The central tenet of ecomorphology links ecological and morphological variation through the
process of selection. Traditionally used to rationalise morphological differences between …

Major shifts in habitat often occur during life history and can have significant impacts on the
morphology and function of an animal; however, little is known about how such ecological …

Recent work showed that two species of hammerhead sharks operated as a double
oscillating system, where frequency and amplitude differed in the anterior and posterior …

Dunkleosteus is a widely-recognized prehistoric organism, yet its life appearance,
paleobiology, and even basic morphology remain poorly understood. A new reconstruction …

The quintessential example of evolutionary convergence is that between the shark,
ichthyosaur, and dolphin. Although not closely related, the three exemplar taxa have …

Accelerative manoeuvres, such as fast-starts, are crucial for fish to avoid predation. Escape
responses are fast-starts that include fundamental survival traits for prey that experience …

The emergence and subsequent evolution of pectoral fins is a key point in vertebrate
evolution, as pectoral fins are dominant control surfaces for locomotion in extant fishes. 1, 2 …

This work presents new information on the morphological aspects, reproductive biology and
