So, we know that fish tend to frequent underwater structures - but somehow people are surprised that this includes offshore wind turbines.
The discovery was made by seal researchers, who spotted that some seals were visiting one column after another. To a seal, the bottom of a wind turbine is basically a buffet. Researchers are now suggesting that it might be possible to site and design turbines to increase this effect and benefit fish and other wildlife...and possibly even fishermen.
Seals are cute.
