Physical Characteristics of Adult and Young

Blue whales are estimated to die at about 80 years old. They are born weighing from 5,000 to 6,000 pounds. These magnificent whales are approximately 23 feet in length when they are first born. The adult blue whale weighs, at average, about 200 tons and are about 80-100 feet in length. The adult has a heart the size of a Volkswagen Beetle.

Mating and Reproduction

Adult female blue whales are pregnant for about eleven months and get pregnant every two to four years. Their young will start mating as well once they get to age of 10. The babies of blue whales, known as calves, are born at about about 5,000-6,000 lbs. They are around 23 feet in length when born.

Special Abilities and Needs

Blue whales have an impressive ability to communicate to other whales across rough waters. Sadly this is affected negatively since there are so many loud ships. If a loud sound interferes with the blue whale's call, it can actually cause them to not know where to go which will eventually impact them negatively.

Niche in the Food Chain

Blue whales do not have any documented predators. The only animal that has been known to attack blue whales are killer whales. Blue whales eat large amounts of krill because they don't have teeth.

Significances

Blue whales are a very well known and a very admired species. There are actually tours that take people on boats so they can possibly see a blue whale in their natural habitat. You can actually email the people at Monterey Bay, blueoceanwhalewatch@gmail.com, to learn more about these tours.

Whaling

Whaling is a very horrible and heinous thing to do. It is now illegal. It caused whales to become well known for being an endangered species. The blue whale thankfully was a faster swimmer so it was harder to catch them.
