Researchers have revealed that the killer whales in Puget Sound are facing decline mainly because of lack of food. Two new deaths have been recorded this year. Researchers have noticed that there have been no new calves since 2012 to increase the number of the killer whales.
Ken Balcomb of Centre for Whale Research said the whales are separating from their pods and dividing themselves into two small groups. It is surprising because they are known to socialize and feed together.
