（单词翻译）

 Females travel in family groups, sometimes leading their young on yearly wanderings of up to 20,000 miles. Each day, they gather to reaffirm their bonds. They seem to crave1 physical contact.  

 
Finally, the mothers disperse2 to feed in shifts. They leave their calves3 for up to 40 minutes of every hour. They may dive up to 2 miles for a daily catch of 300 pounds of octopus4 and squid. This calf5, too young to dive, tracks his mother closely from above, listening intently for her signature clicks.
 
Chunks6 of octopus rise to the surface from the matriarchs hunting below like bread crumbs7 leading back to safety. 
 
From the depths, mother finally returns. All of this young life, the calf has been on the move. Now his mother and aunts seem to be waiting for something big. Unknown to the calf, he’s about to be welcomed into a world of giants, a world rarely seen and little understood. 
 
Migrations8 are "journeys of attrition. Darwinian in the extreme".
