All year round.
Fish, small vertebrates and aquatic invertebrates.
This animal is an excellent swimmer from the mustelid family (such as the badger and weasel) and it is the only one in this group that has amphibiam behaviour. It is relatively rare to see an otter, but mudflats where it occurs are ideal for looking for its distinctive footprints.
Curiosity: These animals like to find places where they can slip on their bellies.
