Herpetological Highlights

Animals make all sorts of noises for all sorts of reasons. Working out what they mean is difficult, especially if the animal is less than honest. This episode is all about the truthfulness of the screams of a little lacertid. Our Species of the Bi-week is a delicate frog.

Colour morphs exist in many species, but are those colours linked to differences in behaviour or success? We look at a polymorphic lizard and whether combat success is linked to three different colour morphs, and maybe why.
