NO qualms about it, Sir David Attenborough is the kind of figurehead who will never need an introduction, his name now synonymous with some of the most weird and wonderful inhabitants of the animal kingdom.

Yet the veteran broadcaster still does not show any signs of slowing the pace anytime soon – not bad going for a man in his mid-80s. He’ll back in Attenborough’s Ark, discussing the ten most endangered animals around the globe that he’d most like to save from extinction.

He explains about Darwin’s frog, so special because it’s the only frog in the world where the male gives birth to its young.

But David’s not done there; among others, he also wants to fill us in on the movements of the solenodon, an ancient mammal; the Sunda pangolin, which has armour made of keratin; and Priam’s birdwing butterfly, which is the largest on earth.
