Herpetological Highlights

Giant garter snakes are big beasts that like wetland areas - we chat about how they get on when faced with the challenge of moving to a new wetland. Then, a brand new species of banded venomous snake has been discovered in Thailand.

Hibernation is a pretty extreme biological process that shouldn’t be undertaken lightly. Bearded dragons are one of many beasts that have it perfected, and in this episode we look at how.
