Two whales, each weighing about 10 tons, were found dead on the Kurils, they washed up on shore, said in a statement on Tuesday the Reserve "Kuril".

There are many hypotheses on this subject: the death of whales explain the change in temperature of ocean currents, failures of orienteering in hunting, disease, and even the number of self-regulation" — said.
