Tropical forest logging has contributed to population declines in many animals, including the Bornean gibbon, known for its whooping call.

Two vertebrate species go extinct every year on average,

These odorant blends act like biochemical uniforms, identifying individual ants

This is a side view of the plesiosaur model in the hydrodynamic simulation. Credit: Ms Pernille V Troelsen When dinosaurs ruled the land, plesiosaurs ruled the oceans. Famous for their incredibly long necks — some of which were up to 7 metres long — plesiosaurs have remained an evolutionary mystery for hundreds of years. Pernille

A new study by Per Henningsson at Lund University, Sweden is the first of its kind to analyse the aerodynamics of bats performing manoeuvers during flight.

The Wilson Journal of Ornithology has just published the results. Praying mantises are carnivorous insects with powerful raptorial front legs that usually depend on arthropods

This photograph shows Coronodon havensteini teeth. Credit: Geisler et al. The blue whale is the largest animal that has ever lived. And yet they feed almost exclusively on tiny crustaceans known as krill. The secret is in the baleen, a complex filter-feeding system that allows the enormous whales to strain huge volumes of saltwater, leaving
