Bats have famously good hearing, and fringe-lipped bats in Panama have tuned theirs to listen out for frogs calling out for mates. But these bats are quite particular about which amphibians they eat. New research has revealed that bats have to learn these skills, as the youngsters have way less idea which frogs they can safely tackle. We finish off talking about a newly described skink from urban China.

Almost all pythons and some boas have heat pits on their faces. This extraordinary adaptation lets these snakes 'see' the heat signature of their unsuspecting prey. A new study has determined the evolutionary history of these amazing attributes, and worked out whether they are more prevalent in snakes with certain lifestyles.

Day geckos and certain plants share a long evolutionary history, with day geckos feasting on nectar and in return pollinating plants. A study from back in the mid 2000s proved this neatly, and we delve into it this episode. After that, we have a snake eating somebody's underwear, and a very novel new method for controlling invasive cane toads in Australia.

This episode is all about the problems rattlesnakes face in the wild. A brilliant new study uncovers whether predatory birds in America are resistant to the toxins of the rattlesnakes they eat, and then we talk about how rattlesnakes deal with the problem of getting water in dry environments. Finally, a beautiful new species of pitviper has been described from Thailand.

Some tree-dwelling salamanders have a remarkable ability to ‘sky-dive’, controlling their descent after leaping away from predators. New research tests the gliding ability of a number of different species, and finds that some are more adept than others. We follow up with a brand new frog species described from Kangaroo Island, Australia.

We are talking about our own work this week, focusing on our latest research into Europe’s foremost colubrid, the Aesculapian snake. We chat about radio-tracking these beasts and dive into some of the media coverage this study has received. Finally, we touch on some good conservation news from the Zoological Society of London.

Salamanders and frogs return to their home pools to breed, but removal of these pools is making life more difficult for them. New research discovers how artificial pools can affect the genetics and fates of both spotted salamanders and wood frogs.
