North American River Otters

Blink and you’ll miss them – otters are extremely fast swimmers. We are home to a bevy of otters, including adults and their pups, as well as an orphan rescue.

Sleek swimmers playfully propel themselves through waves of water

The first thing you’ll notice about otters is how fun they are to watch. Zooming through the water with powerful tails and webbed feet, they can reach speeds of 13 kilometres an hour and hold their breath for up to eight minutes. As acrobatic as they are in the water, river otters are also comfortable on land, making their homes in burrows on the water’s edge.
