Animals have to adapt to all sorts of changes, but urbanisation is perhaps one of the most drastic. Urban noise can majorly interfere with communication, so how do frogs overcome the noise and busyness of the big city?

Is it a bird? Is it a plane? No it’s a Plethodontid Salamander, more specifically Aneides vagrans AKA the wandering salamander. As strange as it sounds we look at a gliding salamander this episode. Species of the Bi-week is an elegant wine-gum-looking beast.

123 Fantastic Mr Foxsnake

Foxsnakes are widely distributed and with an apparently tumultuous taxonomic history, but we can still take a look at the habitats they prefer and their ability to traverse fragmented landscapes.

122 Volcano Lizards

Lizards can live in some tough environments, but does any lizard top the chubby Phymaturus living on the side of an active volcano? This episode we explore how they are coping with repeated ashfall events, as well as highlighting a newly described Phymaturus species.

121 The Cheeky Startler

Toad headed agamas have a bonkers display - bright pink flaps which pop out of the sides of their head. It has long been assumed this serves as a warning to would-be predators, but does scientific evidence support this?
