Herpetological Highlights

Elapid behaviour is not as well studied as we’d like, so in this episode we look at a couple of papers to cover more ground. One describing the changing morphology to optimise caudal luring, and another that looks at just how much you can bother a brownsnake before the worst happens.

The complexities of evolution pose constant questions. One of the most fruitful groups to look at when trying to understand evolution is Anolis lizards. They are well known for repeated convergent evolution, many species, and existing in a wealth of environments; so this episode we look at an example of what can drive that evolution. Also a cryptic viper for Species of the Bi-week.

Back in the 90s the Swiss authorities decided to start digging loads of ponds for their dwindling amphibians. But did these uniquely slippery customers appreciate it?

The islands of New Caledonia are famous for their geckos. Recent research has revealed the evolutionary past of these sticky lizards, and it all began shortly after the islands themselves emerged from the Pacific Ocean.

We’ve chatted about invasive species in many episodes, but this time the invader is INSIDE the better known invader. A parasite has made its way to Florida, USA in the lungs of Burmese Pythons; has the parasite spread, and is it impacting the native snake species?
