This is an Eurasian otter video.
From Wildlife Extra:
February 2012: A group of volunteers rolled up their sleeves to find out more about what otters eat in North Wales – at a special workshop earlier this month.
In the workshop, organised by the Mammals in a Sustainable Environment (MISE) project at Treborth Botanic Gardens, more than 40 volunteers dissected otter droppings, know as spraints, to see what they could find. The remains of eels, marine and freshwater fish, crabs, amphibians and even birds and mice were all among their discoveries – more than 23 different prey species in total.
