The harbour porpoise, as the species found in our waters is called, is a small whale common in northern seas. It is about 1.5 m long and weighs about 50 kg. The favorite food is different kinds of fish, which it often hunts close to costs, but also enjoys it in the open ocean.

The porpoise has become more and more rare the last decades. The main reason for this is that so many are entangaled in fish nets, and because the porpoise breaths air like you and me, this leads to a terrible death through drowning.

In the Baltic Sea, only a fraction of the great numbers of porpoises that could earlier be found here now remains.
