A walrus was sighted on the beach of Schiermonnikoog on Monday.

The last time such an animal was seen in the Netherlands was in 1998 on Ameland.

Seal sanctuary Ecomare on Texel therefore speaks of a "very exceptional" situation.

Walruses are native to the Arctic, which the marine mammals normally never leave.

The walrus on Schiermonnikoog is therefore a vagrant, says a spokesperson for Ecomare.

Wanderers are animals that go very far outside their habitat.

The sighting of the walrus on Schiermonnikoog has been recorded on observation.nl.

According to that website, on which animal spotters can report their observations, it is a female.

The special find was made by Ralf van Hal, researcher at Wageningen University.

He saw the colossus lying on a sandbank, where seals often lie.

In recent days, a walrus has also been spotted in Germany and Denmark.

It is probably the same animal.

Apparently the walrus is uninjured.

Ecomare therefore sees no reason to come to the rescue at the moment.

"If she has come here, she can also go back. And here she can also catch fish," says the spokesperson.

Moreover, according to her, it is very difficult to catch an adult specimen.

"They are very big though."

An adult walrus weighs between 1,000 and 1,500 kilograms. Furthermore, walruses are known for their large tusks and mustache.
