Something strange started happening in early 2023 in the waters off South Western Europe, where the Mediterranean sea meets the Atlantic Ocean.Orcas began slamming into the sides of fishing and sailing vessels. The killer whales then dived underneath to locate and destroy the rudders used to steer the boats. Once finished the Orcas departed leaving shocked crews and thousands of dollars of damage behind. Some of the attacks were over in a matter of minutes but others lasted hours. It’s very unusual behaviour for this particular mammal but Orcas are under a lot of threat from man-made hazards. Factors like underwater noise pollution, overfishing, toxic waste and climate change to name a few are making Orca life extremely difficult. Could all of this have caused this change in behaviour? This week we ask ‘Are Orcas Ok?’Contributors : Billy Heaney, zoologist, wildlife tour guide and presenter.
