This week when I was driving around Norfolk I stopped off at Broads National Park.
While I was there I spotted some otters at the park, which is also home to many of these playful animals. The best way to spot one is by being quiet, hopping in a canoe and patiently waiting until one pops its head up.
Did you know an otter can hold its breath under water for 4 minutes? How long can you hold your breath for?
