The guards point out that the Orcas are very intelligent and are known to follow the boats closely, but it is unusual for them to attack ships repeatedly.
In the last two months, several boats have been damaged in orca encounters and at least one sailor has been released when affected.
In the latest incident on Friday, there was a 36-foot boat near the A Coruna on Spain’s northern coast, when an orca hit it hard about 15 times, the outlet reported.
A similar incident was reported on 30 August when a ship made radioactive to the Coastguard to say that it was “under attack” from killer whales.
On the same day, a Spanish naval yacht, the Mirfak, lost part of its hull to the killer whale encounter.
Then on 29 July, a boat encircled nine boats from Cape Trafalgar in the southwest of Spain.
Orcas reported that Orcas shook the hull for an hour – rotating the boat at 180 degrees, deactivating the engine and destroying the hull, the outlet reported.
The outlet reported that scientists called his recent behavior “highly unusual” and “related”.
Dr. Ruth Esteban has researched the Orcas of Gibraltar for many years and believes that the same group of Orcas are responsible for the events, saying that this is unusual behavior for the species, the outlet reported.
Meanwhile, Spanish maritime authorities warned the ships to “keep a distance” from any orcas.
