The Blue Whale

The blue whale (scientific name balaenoptera musculus) is a subspecies of whale that inhabits the waters of Southern Chile, the Coral Triangle, and the Gulf of California. It is the world's largest animal, growing between 80 and 100 inches long and weighing almost 400,000 pounds. It is also the world's loudest animal, having calls that can reach 188 decibels and low frequency whistles (which are most likely used for mating purposes) that can be heard for at least 200 hundred miles. Its stomach can hold 2,000 pounds of krill (its main food source) at one time, but it needs to eat 8,000 of krill a day to survive.

The blue whale is classified as an Endangered species. It is this close to becoming extinct for three reasons. The first reason is that some of its population is killed as a result of getting hit by ships or getting caught in fishing nets. The second reason is that much of its population was killed by commercial whaling. The third reason is that the krill population is negatively affected by climate change. Because of this, the World Wildlife Fund's (WWF's) efforts to save it consists of working to make the International Whaling Commission (IWC) more effective in removing all of these threats to it. This is being done because it plays an important role in the overall health of its habitat.
