Friendly Giants Far Away From Home: Sightings of Sunfish in Baltic Startle Biologists
A total of four ocean sunfish have been spotted along Germany's Baltic coast over the last week, far away from their habitat in tropical and temperate waters. Biologists say the awkward, slow-moving and friendly giants are likely to have been swept in by storms.
German fisherman Jürgen Krieger shows of his most unusual catch, a 10 kilogram ocean sunfish which got lost in the Baltic.
Maritime experts and beachcombers have been puzzled by the appearance of several sunfish -- strange, disk-shaped creatures that can reach a length of up to 3.30 meters and a weight of over two tonnes -- along Germany's Baltic Sea coast in recent days, thousands of miles away from their normal habitat in tropical and temperate waters around the world.
Götz-Bodo Reinicke, a scientist at the the museum, said he didn't think global warming had driven the fish into the Baltic.
"They're not exactly high-performance swimmers. They're slow dreamers who peacefully drift around the seas and aren't known for lively enthusiasm," Reinicke told SPIEGEL ONLINE.
"They're friendly creatures who look at you in a slightly melancholy way if you've got one in the aquarium. It's not that likely that they actively swam into the Baltic. They may well have been swept in from the North Sea by a sea swell caused by strong winds."
Sunfish, known in German as moonfish (Mola mola in Latin), are flat fish that have large fins on their back and underside. They eat soft matter such as jellyfish and small crabs and are harmless to humans.
"It's a very ungainly fish, I don't know what nature was thinking of when it came up with this one. It must have been playing a joke," Ilka Hasselmeier, a marine biologist at the University of Kiel's Research and Technology Centre, told SPIEGEL ONLINE.
Sunfish occasionally get spotted in the North Sea, although that too is too cold for them, and it is very rare for them to get through the bottleneck of the Skagerrak and Kattegat straits into the Baltic.
"Once we've examined the fish we would like to preserve it for our museum," said Reinicke.
