B+musculus

Class: Mammalia (this class has 5000 species placed in 26 orders.) Family: Balaenopteridea. (Balaenopteridea's are large and remarkably diverse group of mammals. Having 220 species in 10 families. ) Genus: Balaenoptera Carnivore**
 * BALAEOPTER MUCULUS


 * Population:** **Estimated between 1,300 to 2,000, the population of blue whales is dangerously low.

Color: Blue whales are a lightly mottled blue-grey, with light grey or yellow-white undersides.

Size: The largest recorded length for a blue whale is 110 feet, but sizes tend to run more in the range of 80-100 feet. Females are up to 32 feet longer than males. At 100 feet, a blue whale would weigh close to 200 tons, or 400,000 pounds.**


 * Balaeopter Mulucus are endangered;**
 * The blue whale is the largest animal ever known to have existed. In the 20th century, the species was an important whaling target and even after it was protected and commercial whaling stopped in 1964. Although commercial whaling no longer represents a threat, global climate change and its impact on ocean krill.** **On the other hand, the number of blue whales in the Antarctic remains extremely low, and there is a complete absence of blue whales off southern Japan, and blue whales are apparently rare in the Gulf of Alaska and the southern Bering Sea,**

Whales travel to cold waters for feeding, and they go to warmer waters to give birth. They 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 to 4 months on the rich supply of krill. During this migration, they eat virtually nothing for at least 4 months and live on body reserves,( the fat). Females give birth in warm tropical waters because the young only have a thin layer of blubber to keep them warm. Females give birth to a single calf about 7m long and weighing 2.5 tonnes.**
 * Migration:

Blue whales are carnivores,** **although they only eat very tiny things, no bigger than your pinky finger. Their favorite food is krill, or shrimp-like, that are up to three inches long. Blue whales must eat two to four tons of krill a day during the feeding season to survive the rest of the year.**
 * BALAEOPTER MUCULUS DIET:


 * The ways Balaeopter Muculus, or Blue whales are being safe are that countries is that they are making laws for whaling and they are also they are getting people to have clubs to help and try and save endangered animals. Global warming is one of the main causes so its mostly up to us to help save the planet for the animals in it. Also polution is another problem, we need to solve because animals in the ocean, in paticulur are getting killed, mistaken it for food, so they choke and die. We could help with recycling the right way, and try to do something about global warming.**
