Raging killer whales are launching terrifying ‘orchestrated’ attacks on boats injuring sailors – and no one knows why
SCIENTISTS have been left confused by a series of incidents in which killer whales have hit sailing boats along the Spanish and Portuguese coasts.
In some cases, boats have been damaged and at least one crew member suffered bruising from the impact of the ramming.
Two boats also lost parts of their rudders due to the impact of the attacks, according to reports.
Incidents have been reported in several locations, including one just off A Coruña, on the northern coast of Spain, on Friday afternoon.
Pete Green, managing director of Halcyon Yachts, told a boat was being taken to the UK when an orca rammed its stern at least 15 times.
As a consequence of the impact, the vessel lost steering and was towed into port to assess damage.
To hunt, killer whales use their massive teeth, which can grow up to 4 inches (10cm) long.
Killer whales are mainly found in the open ocean, but can also be in coastal waters.
Orcas are known to attack great white sharks too, consuming their oil-rich livers, says .
