The Springwatch team are joined by fieldcraft experts Simon King and Charlie Hamilton James for an in-depth view of one of the UK's most charismatic yet enigmatic animals - the otter. Living not only along our rivers but also at the coast, otters have remarkable adaptations to a life both in and out of water. The team bring you the very latest scientific discoveries as well as a review of the turbulent history of the otter in the UK. It looks like the otter is making a steady comeback around the country but not everybody agrees this is good news.
