Dusk. The Blue Whale [Balaenoptera musculus] is the largest animal ever known to have lived on Earth, growing to 33 metres [110 feet] and a weight of at least 180 metric tons [200 short tons]. The largest known dinosaur was Argentinosaurus, which is estimated to have weighed up to 90 metric tons [100 short tons]. Blue whales can live for at least 80 years. Long and slender, the Blue Whale's body can be various shades of bluish-grey dorsally [sometimes appearing quite dark] and lighter underneath. As with other baleen whales, its diet consists almost exclusively of small shrimplike crustaceans called krill. Blue Whales were abundant in nearly all the oceans until the beginning of the twentieth century. For over 40 years, they were hunted almost to extinction by whalers until protected in 1966. The IUCN Red List counts the Blue Whale as Endangered. Blue Whales can reach speeds of 50 kilometres per hour (30 mph) over short bursts. Prominent on the coastline is Mauao, also known as Mount Maunganui, an extinct volcanic cone at the end of a peninsula and the suburb of Mount Maunganui [part of Tauranga City], by the eastern entrance to the Tauranga Harbour. The highest point is 232 metres above sea level.
