Scientists have filmed an ancient egg-laying mammal named after Sir David Attenborough for the first time.

Until now, the only evidence that this species of long-beaked echidna existed was a decades-old museum specimen of a dead animal.

Dr James Kempton from Oxford University was lead researcher of the team that recorded the images in the Cyclops Mountains of eastern Indonesia. He's been speaking to Newshour's Krupa Padhy.
