While Island Hopping in the Sea of Cortez, we encountered the largest animal on earth, the majestic blue whale. Reaching a length of over 100 feet, blues sustain themselves on a diet of krill, a tiny crustacean. Hunted to near extinction in the 1920’s, blue whales are thought to use the Sea of Cortez as a nursery area.



Baby blues are born 25 feet in length and 6000 pounds. Consuming 100-150 gallons of milk per day, calves may gain 10 pounds per hour and are weaned after 6 months.

The California coast supports the world’s largest concentration of blue whales. Monterey Bay is a summer feeding ground for the endangered blue whales.
