Herpetological Highlights

Common knowledge suggests that albino animals are rare in the wild because they stick out like a sore thumb and get eaten by predators, but studies supporting this are relatively scarce. Now, researchers from Australia have discovered that the drawbacks of albinism are not limited to their obvious appearance. Even better, they used our old friends cane toads to prove it.

New methods in antivenom technology may yield a treatment that works on most of the cobras in Africa, thanks to the blood of alpacas and some very clever scientists. Then we follow up with two new species of sleepyhead snake from Venezuala.

Urban areas represent both opportunities and risks for animals, and they adapt their behaviour in many ways to cope with this fast-paced lifestyle. Now, a new study has detailed how urban wall lizards in Croatia have richer social lives than their rural counterparts. Then we chat about a listener-submitted story detailing wild lizards eating pizza.

Research from Asian geckos generally suggests that sticky pads are used for smooth surfaces, while claws help grip onto rougher surfaces like wood and rocks. But a new study using Australian geckos is has turned that paradigm upside-down. Then we talk about a brand new species of frog described from the mountains of central China.

Toads continue to amaze us - this time they are using their sense of the Earth's magnetic field to find their way home. But how important this sense is for cane toads as they travel home from long journeys, and how much are they relying on their sense of smell, was a mystery, until a clever new study tested the toads. Then we briefly touch on how pythons digest bones so successfully.
