Researchers recently solved the enigma of how the strategy of some toxic species that use colored signals to warn predators came about. Common in Europe, the color of the spotted salamander acts as a ...

Animal communication takes many forms. Subscribe to our newsletter for the latest sci-tech news updates. It can include sounds and bioacoustics, as well as smells and pheromones. But other signals, ...

Abstract Aposematic prey use conspicuous warning signals to advertise their defenses to predators. It has long been recognized that the efficiency of a warning signal may be reduced if poorly defended ...

New findings help answer a particularly vexing evolutionary question: how do species that use bright coloration to keep predators away survive long enough for this warning signal coloration to evolve, ...

Why are some animals, for example, frogs, snakes and butterflies, brightly coloured for self defence, and in this context what is aposematism? Mechanisms for defence against predators takes many forms ...

Also known as warning colouration, this refers to how animals change colour or adapt physically to counter threats from various predators. Such features warn predators to refrain from attacking an ...
