The latest incident saw a Bryde's whale become tangled in octopus trap ropes and die.
The whale’s carcass floated to the surface and had to be hauled to shore - a very expensive operation, according to Craig Foster of the Sea Change Project, a non-profit organisation made up of volunteers, scientists and conservations journalists who study various aspects of marine life.
Foster said that for about 15 years, a company that has been fishing for octopuses in the area had caused huge problems to the marine life there, with many animals getting caught in its traps, including whales.
“They’ve killed at least eight whales in the last two years. The number could be higher, we aren’t sure how many have been entrapped and got freed, we aren’t sure how many are out there injured it probably struggled and drowned after a torturous day,” Foster said.
