Whales are commonly called warm-blooded, they breathe air, give birth to live young and nurse their young. They even have hair! These characteristics are common to all of us.
Whale migration is an endless cycle of life. Every year, whales migrate toward the colder poles in the summer for food and toward the more tropical waters of the equator in the winter to give birth.
There are over 80 species of whales, and each has their own movement patterns; Gray whales are thought to have the longest migrations traveling 10,000 -12,000 miles round-trip between Baja California to the seas off Alaska and Russia. The migration routes and distances of many whale species are still relatively unknown and one thing sure is we see the powder of life.
While the heyday of whaling ended a while ago, whaling stills occurs in some areas, but whales are threatened even more by ship strikes, entanglements in fishing gear, fisheries bycatch, and pollution.
