Thar She Blows!
The great annual grey whale migration is one of the most extraordinary migrations on the planet. Their journey begins in the Arctic, and they travel a distance of over 6,200 miles to reach the southern Baja California lagoons to perform their reproduction cycle and nurse their calves. They bear their calves every other year, alternating each year between mating and birthing.
An adult whale measures between 46 and 55 feet and weighs up to 88 tons. A baby whale size at birth is between 13 and 17 feet long and weighs from 1.6 to 2.2 tons. At the end of lactation (around 6-9 months) they weigh around 17.5 tons. It is said that the whales possess a strong maternal instinct and that the relation with their offspring is close and sensitive.
