  2. CHARECTRISTICS http://www.antarcticconnection.com/antarctic/wildlife/whales/blue.s html - Largest of Earth's animals - The majestic Blue whale can be found in all the world's oceans. - In summer, they swim frequently around the polar ice shelves, moving to tropical and subtropical waters during the winter. - They travel alone or occasionally in pairs, with the larger individuals occurring the farthest south. - Once numbering close to 200,000 individuals, Blue whales were heavily hunted for their oil, meat, and baleen during the early to mid 1900's, severely reducing the species' population to near the point of extinction. - Since the International Whaling Commission (IWC) imposed a hunting ban in 1966, Blues have returned to several areas of their former range, but recovery is slow (current populations are only 1% of their former numbers).

  3. Population: 11,000 individuals Location: All oceans Size: 85 to 100 ft long Weight: 85 to 150 tons http://www.antarcticconnection.com/antarctic/wildlife/whales/blue.shtml

  4. WHAT IT EATS Diet: Krill & other tiny Crustaceans http://www.antarcticconnection.com/antarctic/wildlife/whales/blue.shtml

  5. WHERE BLUE WHALES LIVE Blue Whales live in all oceans world wide. http://www.antarcticconnection.com/antarctic/wildlife/whales/blue.shtml

  6. HABBITAT The blue whale is found mostly in cold waters. It prefers deeper ocean waters to coastal waters. The blue whale occurs in the Icelandic & Celtic Marine Ecosystems and Southern Caribbean Sea. Also, approximately 2,000 blue whales live off the California Coast and migrate to Mexico, and Costa Rica. http://www.blue-whale.info/Blue_Whale_Habitat.html

  7. ADAPTION TO THE ENVIRONMENT 1.A baleen whale swims with up-and-down strokes of its powerful tail flukes. Muscles in the upper and lower regions of the caudal peduncle (tail stalk) provide power 2.Rorquals are more streamlined than other baleen whale families, and they swim fastest of baleen whales. The fastest can reach probably approach speeds of 32 kph (20 mph). 3. Other species travel at slower speeds. Gray whales migrate at about 10 to 11 kph (6-7 mph). 4. The thick layer of blubber under the skin of a whale results in a streamlined, fusiform body, making a whale energy-efficient for swimming. http://www.seaworld.org/animal-info/info-books/baleen/adaptations.htm

  8. MIGRATION Winter: warm, low latitude tropical waters (breed and give birth) Summer: cooler, high latitude polar waters (feeding) Most blues are migratory and travel thousands of kilometres annually between their winter breeding grounds in warmer, low latitude waters around the tropics, where they mate and give birth, and their summer feeding grounds in the cooler, high latitude waters of either the Arctic and Antarctic, where they feed for 3-4 months on the rich supply of krill and other food which occur in huge numbers in polar waters. http://www.whaleroute.com/migrate/
