Largest body part

The largest body part is either the largest given body part across all animals or the largest example of a body part within a species. The largest animals on the planet are not the only ones to have large body parts, with some smaller animals actually having one particularly enlarged area of the body. The largest organ of a mammal is its skin.

Across all living animals

Blue whale

Unsurprisingly, as the largest animal alive, the Blue Whale has the largest instance of several body parts.

  • Its tongue weighs around 2.7 tonnes (3 short tons)
  • Its mouth is large enough to hold up to 90 tonnes (100 short tons) of food and water.
  • Its heart typically weighs 600 kg (1,320 lb) and can reach 900 kg in exceptional cases
  • Its aorta is about 23 cm (9 in) in diameter.
  • Its penis is about 2.4 m (8 feet) in length.

Other animals

  • The Atlantic Giant Squid has the largest recorded eyes of any animal with an approximate diameter of 50 centimetres (20 inches), although those of the Colossal Squid are thought to reach an even greater size.
  • The giraffe has the longest neck as well as the longest tail of any land mammal.
  • The Wandering Albatross has the largest wingspan at 3.63 metres (11 feet 11 inches).
  • The longest horns ever recorded belonged to a Wild Asian Water buffalo and measured 4.24 metres (13 feet 11 inches) from tip to tip. The Greater Kudu has the longest horns on average.
  • The largest and heaviest brain belongs to the Sperm Whale, weighing around 9 kilograms.
  • The Arctic Lion's mane jellyfish is the longest animal; the biggest had a bell (body), with a diameter of 7 feet 6 inches and the tentacles reached 120 feet. It was found washed up on the shore of Massachusetts Bay in 1870. Bootlace worms can reach great lengths. A specimen was measured at 55m (180 feet) but this may be unreliable as the body is somewhat elastic.

In proportion to body size

  • The Tube-lipped Nectar Bat has the longest tongue of any mammal in relation to its body size. Its 3.4 inch tongue is 1.5 times longer than its body, and must be kept inside its rib cage.
  • The barnacle is the creature with the largest penis as a proportion of its overall body size.
  • Among vertebrates, the Argentine Blue-bill duck has the longest penis in relative to its body size.
  • The vampire squid has the largest eyes of any animal relative to its size.
  • Humans have the largest brains in relation to body size.

Humans

  • The longest bone in the human body is the femur.
  • The largest artery is the aorta and the largest vein is the inferior vena cava.
  • The largest internal organ is the liver. It is also the heaviest organ, with an average of 1.6 kilograms (3.5 pounds).
  • The largest external organ, which is also the largest organ in general, is the skin.
  • The longest muscle is the sartorius muscle in the thigh.
  • The longest single nerve is the sciatic nerve in the thigh, counting its branches and axons.

Records

  • The longest human tongue ever recorded was that of Stephen Taylor and measures 9.5 centimetres (3.74 inches). The longest tongue for a female is that of Annika Irmler at 7 centimetres (2.76 inches).
  • The woman with the longest legs is Svetlana Pankratova. At a height of 6' 4", her legs measure 52 inches.
  • The woman with the longest fingernails is Lee Redmond. The total length of her fingernails is 7.513 meters.
  • The longest head of hair belonged to Xie Qiuping of China and measured 5.627 metres (18 feet 5.54 inches) on 8 May 2004.
