A pod of blue whales has been spotted off the coast of San Diego in the past couple days. An expert says they’ll be staying until the end of the month.
The whales are feeding rather late in their migration pattern. Usually, this time of year, they have migrated north, said whale expert John Hildebrand with the Scripps Institution of Oceanography.
Cold currents from the north met warmer waters from the south on the San Diego coast. This created nutrient-rich waters for whales to feed on.
Blue whales are the largest animal in the history of the earth, Hildebrand said.
