These Otters May Smell Prey as They Swim

Although most Eurasian otters (Lutra lutra) spend their time scouring inland river bottoms for prey, those along the coast of Scotland’s Shetland Islands are able to take advantage of the kelp forest’s oceanic bounty. More than a thousand of the semi-aquatic mammals live here, making the Isles’ coastline home to one of the densest otter populations in Britain.
