Atlantic orcas 'learning from adults' to target boats

A strange, dangerous game of targeting and ramming into small sailing and fishing boats is spreading through a population of orcas off Spain's coast.

Scientists say at least 20 Iberian orcas have now learned the behaviour by copying their elders.

It is believed that one or two orcas started interacting with and damaging small sailing vessels in 2020.

Scientists told the BBC the animals appear to be "playing" with the boats rather than acting aggressively.
