Some species come in different colour morphs, but how do species maintain these different morphs? Do they end up behaving differently? This episode we look at the territorial behaviour of salamanders in North America, and check in on a whole bushel of tiny chameleons for the Species of the Bi-week.

The mirror test is often used to try and determine if animals have self recognition. If they recognise it is them in the mirror, they will react to a change in their appearance. But for snakes, sight is not the primary sense, so scientists have had to get a bit more creative.

This episode we chat about the thousands of frog ancestors whose stories can still be heard in the DNA of modern frogs. How did these frogs from the past deal with dramatic changes, and is modern urbanisation having a sizable effect today?

This episode is all about questioning the assumption that snake male-male combat is driven by competition for mates. We look at a paper that presents evidence showing that food might be behind the combat. Species of the Bi-week returns for a variable and vibrant viper.
