Otter

Otters are semi-aquatic animals that are intelligent, peaceful and loyal. They happen to be fish-eating creatures that only eat fish for breakfast, lunch, and dinner. Otters can sometimes live in lakes or rivers and also build homes. They are great swimmers and they sometimes work together as a pack to hunt the fish which include Trout.

Otters were first mentioned in The Magician's Nephew, where they were summoned with many Talking Animals where they gather around in the council of Aslan after Narnia was created. They also chase Andrew Ketterley with many different animals and decide to keep him as a pet and later seen in the coronation where King Frank I and his wife Queen Helen become the first king and queen of Narnia.
