This is the moment tourist boats chase a pod of endangered fin whales off the southern Spanish coast, sparking fury among animal rights groups.
The footage was filmed by members of the NGO Edmaktub, dedicated to the scientific study of whales and the aquatic environment.
It shows high-powered tourist speedboats racing up to the pod, sometimes shadowing them from just a few metres away.
The tourist boats were filmed apparently chasing the fin whales (Balaenoptera physalus) off the Costa Blanca in south-eastern Spain over the weekend of 24th to 26th June.
Edmaktub said the situation is very dangerous for whales because they can easily become disorientated when they are forced to change direction to avoid hitting a chasing vessel.
The NGO said researchers were working off the coast of Denia in Alicante Province as part of the project Cabo Rorcual, in cooperation with the Valencia Polytechnic University, to monitor the whales’ migration from the Catalan coast in north-eastern Spain.
Edmaktub said the situation is very common at this time of the year.
Association president Eduard Degollada, 56, told Newsflash that it is not uncommon to see boats approaching the marine animals so tourists can take close up photos.
He said: “The boats approach them a lot and the whales are forced to change direction and speed so they end up altering their natural rhythm.
“One of them even has a large scar in the dorsal area that probably happened a few years ago.”
Degollada said the whales usually feed off the Catalan coast from spring until June or July and then migrate south, occasionally crossing the Strait of Gibraltar.
According to Degollada, the fin whales also suffer from excess noise caused by the tourist boats in the area.
He told Newsflash that the noise “drowns out what they can listen to and forces them to change direction and separate from each other, possibly never finding each other again.
“If a calf is separated from its mum, it could find itself heading to the coast, which is certain death for them.
“If they end up stranded, they cannot breathe properly and end up suffocating.”
He added: “A collision with a boat may not cause death, but the continued stress can make it happen.”
Degollada told Newsflash that whales need to be given “a distance of around 300 metres” by law, adding that fines of around EUR 200,000 (GBP 172,000) apply for anyone caught getting too close.
However, he said many people are not aware of the laws in place and Edmaktub works to raise awareness of the situation in the local area.
He also believes that the local authorities need to monitor the coast more closely to prevent whales being harassed by vessel owners similar to how they are apparently chased in the footage.
