Get to know the greater weever

The greater weever is long. It has yellow, blue and green spots and stripes. Its mouth turns upward, and its eyes are close together. On its short dorsal fin and on its gill covers are poisonous spines that the greater weever raises when it feels threatened.

Sleeps during the day

The greater weever is active at night. During the day it burrows at the bottom with only its eyes visible. At night the greater weever goes hunting for prey.

Poisonous fish

You can get stung by a greater weever if you step on it while swimming or if you catch one. It stings, but it is seldom serious. The greater weever isn't just Denmark's most poisonous fish, but the most poisonous in all of Northern Europe.

A delicious food fish

In Denmark, the greater weever is eaten only on the island of Læsø. But the greater weever is a good food fish. In France and Spain it is considered a delicacy.

Catch a greater weever

The greater weever is easy to catch because it bites at any bait. Fish for it during the summer in the Kattegat. This is when it is found close to the coastline. If you're on the lookout while snorkelling, you may be lucky enough to see a greater weever burrowing at the bottom. But be careful that you don't sting yourself on its poisonous spines.
