Shape-shifting sea snakes – a dynamic story of powerful selection pressures and rapid evolution

Evolutionary biologists are tasked with understanding the great diversity of organisms around us. For all we have discovered about the natural world, there is still so much yet to be understood. Researchers at the University of Adelaide‘s Environment Institute are using comparative approaches to understand how phenotypic diversity evolves by the process of natural selection, […]

The evolution of colour vision in sea snakes

Research from the University of Adelaide has revealed the evolution of colour vision in front-fanged snakes following their transition from terrestrial to fully marine environments. This research also provides the first evidence of where, when and how frequently the species have adapted their ability to see in colour. Today, the journal Current Biology published the […]

Sea snakes avoid predators by “seeing” tails

New research has revealed the fascinating adaptation of some Australian sea snakes that helps protect their vulnerable paddle-shaped tails from predators. An international study led by the University of Adelaide shows that several species of Australian sea snakes can sense light on their tail skin, prompting them to withdraw their tails under shelter. The study […]
