August: Building Blubber to Last for Months
It's August. Migration and mating are just weeks away, and whales keep feasting in order to be ready. They must gain blubber enough to sustain them during the months ahead. A 30-ton whale will expend so much energy on the migration to the Baja lagoons that it may lose up to eight tons of its blubber. Little or no whale food is available in the breeding grounds, so this is their time to eat!
