Eddie the otter suffers from arthritis, so his keeper has come up with a novel way for him to improve movement in his joints - basketball.
But visitors to Oregon Zoo, where he lives, will not be able to see him doing it - he only does it in the privacy of his training pool.
Louise Minchin and Charlie Stayt explain.
