Eurasian river otter (Lutra lutra) having caught Greater spotted dogfish (Scyliorhinus stellaris). The otter took only the innards of the dogfish by opening a short section of skin behind the pectoral fin (see images under 'Greater spotted dogfish'). The rest of the fish, still alive, was left on the shore and never retrieved. Perhaps the tough shark skin and battling fish are too much work when other food is plentiful? Hebrides, Scotland
