Down a platypus burrow
Looking more like it should belong to a duck, the platypus's beak is rubbery and contains horny plates with which it can grind up the small invertebrates it finds underwater. Sensing the tiny electric currents produced by all animals with its bill, the platypus finds food even with its eyes closed. Until recently, no one had managed to breed platypuses in captivity and little was known about what happened inside the breeding chamber. Using a small probe camera, the secret underground life of the platypus is revealed.
