New study unlocks mystery origin of iconic Aussie snakes
New research led by the University of Adelaide has found the first tangible evidence that the ancestors of some of Australia’s most venomous snakes arrived by sea rather than by land – the dispersal route of most other Australian reptiles. In a paper published in Genes, the researchers analysed the genomes of two Australian elapids (front […]

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 […]

eScience. Seasnakes sensitive to underwater vibrations
Snakes scare the bejeezus out of many people and seasnakes even more so. It’s therefore no surprise that conservation efforts so often neglect our underwater serpent friends. It turns out though that seasnakes are far more impressive than we thought and are basically Jedi of the ocean. Seasnakes have a sensory organ on their head which […]

A PechaKucha Night of Science
A PechaKucha Night of Science is coming to the South Australian Museum! For the uninitiated, PechaKucha is a presentation style in which presenters showcase their ideas through 20 slides, shown for 20 seconds each. Its a fun and fast-paced approach to presentations. The PechaKucha Night of Science is in celebration of National Biodiversity Month and will feature […]

Sea snakes swim their way to media glory
Research by the Environment Institute’s Jenna Crowe-Riddell has made international headlines, following media coverage of her research into sea snakes in Science Daily, Australian Geographic, Cosmos Magazine and more. The research, which was published in Open Biology, uncovered an extra sense for sea-dwelling snakes. “Land snakes and many lizards have small raised structures on the […]

Media Release: Sea snakes have extra sense for water living
The move from life on land to life in the sea has led to the evolution of a new sense for sea snakes, a University of Adelaide-led study suggests. The international team, led by researchers in the University’s School of Biological Sciences, studied tiny and poorly understood structures on the heads of snakes called ‘scale […]

Making sense of seasnakes
Sea snakes are an under-studied and little understood creature. It is exactly this lack of information that compelled University of Adelaide PhD student and evolutionary biologist Jenna Crowe-Riddell to study them. Jenna is a Fullbright Scholarship holder completing her honours studies under the supervision of Dr Kate Sanders. She was recently interviewed by Radio Adelaide’s The Sound of […]
Study highlights the viviparous sea snakes as a promising system for speciation studies in the marine environment
A new paper involving Environment Institute members Kate Sanders and Michael Lee (also SA Museum) as well as Arne Rasmussen (The Royal Danish Academy of Fine Arts), Mumpuni (Museum Zoologi Bogor), Johan Elmberg (Kristianstad University), Anstem de Silva (Gampola, Sri Lanka) and Michael Guinea (Charles Darwin University) has recently been published in the journal Molecular […]
