National Geographic’s Great Migrations, a seven part series which premieres November 7th, calls itself a collection of “the most moving stories on Earth”. It focuses on some amazing animals from around the world and the incredible journeys they take to survive. This series was a massive undertaking, with the National Geographic crew spending 2 years traveling more than 420,000 miles over 20 countries. The end result is visually spectacular, full of fascinating science and rich in never-before-told stories of animal behavior. The series itself is an great educational resource, and the website has plenty to offer teachers (particularly the Science page and the Teacher Resources page).
While many of the best-known migrations involve land animals or birds, some marine migrations are also pretty darn great.
