Sea otters

Sea otters

National Aquarium Denmark’s new residents

Now you can visit our cute sea otter from Alaska at The National Aquarium Denmark’s where we have built new facilities, which are specially adapted to their antics.

Meet the playful sea otters 


Havodder MoJoe2Gender: Mal
Weight: 28 kg.
Rescued: 23rd June 2010

Struck by a boat
Mojoe is the older of the two sea otters at National Aquarium Denmark. He was found alone in Homer, Alaska, when he was four months old.

Mojoe had a broken jaw and several cuts, suggesting that he had been hit by a boat. The staff at the Alaska SeaLife Center worked very hard to get him healthy and within months he had made a full recovery.

Mojoe is a beautiful sea otter, and is easy to recognize because he is bigger than the female Agnes. Moreover, his face is lighter in colour – indeed it may even look like he has a white beard like Santa.



Gender: Female
Weight: 18 kg.
Rescued: April 14, 2013

Agnes was just a day old when she was found alone at Tutka Bay in Homer, Alaska. She weighed just 1.5 kg. As Agnes was so young the zookeepers had to act as her mother-sea otter. In the beginning they gave her bottle feeding and grooming her after a swim. A month later she was ready to eat small clam treats. Today she eats lots, mussels and squid, etc..

Agnes is very interested in people and has a curious and courageous personality. She is the first mover and does not hesitate to check out new scenarios.

Unlike Mojoe, Agnes has a dark face, which will lighten as she gets older. Another of Agnes’ specialties is that she has mastered the art of doing backward somersaults in the water. She is also vocal.

Did you know

Sea otters have the thickest fur of all mammals
A sea otter’s coat has up to 155,000 hairs per. square centimeters compared to a human head which has about 100,000 hairs in total. Sea otters have no blubber like other marine mammals. Their only insulation against the cold water is the air between the hairs in the coat.

It is vital for sea otters that their fur is clean
Sea otters spend four to six hours a day grooming their hair and removing food debris, dirt or oil with their paws and claws. If their coat is not completely clean, it loses the water-repellent properties that keep the sea otters body warm and dry.

The mother wraps seaweed around her young while she is out finding food
Seaweed prevents the baby from drifting away. Sea otters gather their food – for example sea urchins, crabs and shellfish – on the seabed. They live along the coast where the water is rarely deeper than 30 meters.

Meet our zookeepers

Before the sea otters arrived in Denmark our zookeepers had already been to Alaska to learn all about them. The sea otters are keeping our zookeepers very busy as they require a lot of training and feeding. We have purchased toys to them and you can come and see Mojoe and Agnes playing with them.
