The Blue Whale (Balaenoptera musculus) is a mammal which belongs to the baleen whales suborder. They are filter-feeders, using their baleen to strain plankton out of the seawater. The Blue Whale is the largest animal known to have ever lived, at up to 30 meters in length and 150 tons or more in weight. The blue whale has a tiny dorsal fin, visible only briefly during the dive sequence. It has a spectacular 9 m vertical single column blow. Its lung capacity is 5,000 litres. Blue whales can reach speeds of 30 mph (50 km/h), but 12 mph (20 km/h) is more typical.

The Blue Whale is one of seven species of whale in the genus Balaenoptera. The species has been classified into three subspecies: B. m. musculus, consisting of the north Atlantic and north Pacific populations, B. m. intermedia, the Southern Ocean population and B. m. brevicauda (also known as the Pygmy Blue Whale) found in the Indian Ocean and South Pacific. This subdivision into three subspecies is still questioned by some scientists; genetic analysis may yet show there are just two true subspecies. The specific name musculus is Latin and could mean "muscular", but it can also be interpreted as "little mouse." Linnaeus would have known this and, given his sense of humor, may have intended the ironic double meaning.
