Whale researchers have reported that high percentage of visitors has witnessed orca whales in the Pacific Northwest in large numbers. The whales are also known as exotic or outer-coastal orcas. According to Center for Whale Research, these killer whales, which eat other mammals, have been spotted near Vancouver Island in British Columbia and the Strait of Juan de Fuca.
The outer coastal orcas that were sighted near the island are usually inhabited in the California continental shelf. However, Ken Balcomb from the Center for Whale Research said that it is not completely unusual to see few individual mammals wander around here and as far as Alaska.
