Part 2 - Land Invaders
Amphibians invaded by evolving some of the most bizarre life-histories on the planet. We discover the biggest salamander on earth, a newt with an aphrodisiac tail and a worm like amphibian, the female of which feeds her skin to her babies. The most diverse and engaging amphibians are the frogs, here Panamanian golden frogs communicate by semaphore, a jewel-like poison-arrow frog displays parenting skills and escapolgist tadpoles evade predatory wasps.
