Kiki Saker, 6, looks through her binoculars in search of a Pacific Gray Whale as her mother, Heather Thompson looks on during Heal the Bay and the Santa Monica Pier Aquarium's “Whale of a Weekend” on Saturday. The annual migration of the Pacific gray whale migrates from Alaska to the warm lagoons of Baja California about this time each year. The whales tend to stay in the peninsula for several months in efforts to mate and give birth to their calves before traveling back up to the chilly arctic. The gray whales’ annual migration habits are one of the longest of all mammals (approximately 10,000 to 14,000 milesround trip), according to the American Cetacean Society. Each year, they begin their southward journey right before the winter, taking between two and three months to arrive at the lagoons.
