The largest organism in the world, according to mass, is the aspen tree whose colonies of clones can grow up to 8 kilometres long. The largest land animal classification is also dominated by mammals, with the African bush Elephant being the largest of these. Since no scale can accommodate the whole body of a large whale, most whales have been weighed by parts.
About Largest organisms in brief
This article lists the largest species for various types of organisms, and mostly considers extant species. The largest organism in the world, according to mass, is the aspen tree whose colonies of clones can grow up to 8 kilometres long. The giant sequoia is the largest single-stem tree by wood volume and mass. The blue whale is believed to be the largest animal to have ever lived. The African bush elephant is now listed as two species, the African elephant and the African forest elephant. The title of the longest non-colonial animal is probably owned by Lion’s mane jellyfish, which can grow to several inches in length. A member of the infraorder Cetacea, the blue whale, is thought to be largest animal ever to have lived. Since no scale can accommodate the whole body of a large whale, most whales have been weighed by parts. The heaviest living animals are all cetaceans, and thus also the largest living mammals. The Pyrosanoma is a rigid, cylindrical tube which may be up to 60cm long and 4–6cm wide. It is present in the northwestern Atlantic Ocean, around the coasts of Greenland and Newfoundland, but is less common here than in the east. It occurs only at depths between 10 and 13 metres. The largest thaliacean, Pyrosa, may be a rigid tubeish pink, pink, yellow, or pink, pale pink, tubeish creature which occurs in the eastern Atlantic Ocean.
It may be less common in the west but is found in the north and east of Canada and the U.S. It has a diameter of up to 14 centimetres and is found at depths of 20 and 40 metres in the Atlantic Ocean,. The largest tunicates are Synoicum pulmonaria, which are up to 40 and 40 centimetre long and up to 4 cm wide. The Great Barrier Reef is the world’s largest structure composed of living entities, stretching 2,000 km, but contains many organisms of many types of species. Some organisms group together to form a superorganism, but such are not classed as single large organisms. If considered singular entities, the largest organisms are clonal colonies which can spread over large areas. In 2006 a huge clonal colony of Posidonia oceanica was discovered south of the island of Ibiza. At 8 kilometres across, and estimated at around 100,000 years old, it may be one of the largest and oldest clonal Colonies on Earth. The biggest land animal classification is also dominated by mammals, with the African bush Elephant being the largest of these. It was a male measuring 10. 67 metres from trunk to tail and 4. 17 metres lying on its side in a projected line from the highest point of the shoulder to the base of the forefoot, indicating a standing shoulder height of 3. 96 metres. It is estimated however that this individual could have a mass of 250 tonnes.
