Underwater power cables laid along the sea floors for offshore wind farms are ‘mesmerising’ brown crabs and causing biological changes that could affect their migration habits, a new study reveals.

Experts in Scotland found exposure to electromagnetism triggered ‘behavioural and physiological responses’ in around 60 brown crabs at the St Abbs Marine Station.

This causes cellular changes in the crab species, affecting blood cells and possibly even making them more prone to infection, they warn. 

Oddly, the cables for offshore renewable energy also emit an electromagnetic field that attracts the crabs and causes them to become stationary, which affects breeding and birth control pills abortions op ed migration, according to the team.
