A model of a skeleton of a Blue Whale, the largest animal on Earth.

The largest body part is either the largest given body part across all living and extinct organisms or the largest example of a body part within an existing 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.

Living animals[edit]

Giraffes are instantly recognisable for their long necks.

Blue whale[edit]

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)[1]
  • Its mouth is large enough to hold up to 90 tonnes (100 short tons) of food and water.[2]
  • Its heart typically weighs 600 kg (1,300 lb) [1] and can reach 900 kg (2,000 lb) in exceptional cases[3]
  • Its aorta is about 23 centimetres (9.1 in) in diameter.[4]
  • The blue whale's penis typically measures 8–10 ft.[5]

Other animals[edit]

  • The giant and colossal squids have the largest recorded eyes of any living animal, with a maximum diameter of at least 27 cm (11 in).[6] Only the extinct ichthyosaurs are known to have had larger eyes.[6]
  • The giraffe has the longest neck of any land mammal.[7]
  • The Wandering Albatross has the largest wingspan at 3.63 metres (11 feet 11 inches).[8]
  • The longest horns ever recorded belonged to a wild water buffalo and measured 4.24 metres (13 feet 11 inches) from tip to tip.[9] The greater kudu has the longest horns on average.[citation needed]
  • The largest and heaviest brain belongs to the sperm whale, weighing around 9 kilograms.[10]
  • The Arctic lion's mane jellyfish may be the longest animal; the biggest had a bell (body) with a diameter of 2.28 meters (7 feet 6 inches) and the tentacles reached 36.5 meters (120 feet). It was found washed up on the shore of Massachusetts Bay in 1870.[11]
  • Bootlace worms can reach great lengths. A specimen was measured at 55 m (180 ft) but this may be unreliable as the body is somewhat elastic.[12]

In proportion to body size[edit]

  • The Morgan's Sphinx hawk moth has the longest proboscis in relation to its body size. Its 25–30 cm proboscis is over 3 times longer than its body. It is also known as Darwin's Moth because Charles Darwin predicted its existence some 40 years before it was discovered from experiments he did on an orchid with a "foot long" nectary.[13]
  • The tube-lipped nectar bat has the longest tongue of any mammal in relation to its body size. Its 85 mm (3.3 in) tongue is 1.5 times longer than its body, and must be kept inside its rib cage.[14]
  • The barnacle is the creature with the largest penis as a proportion of its overall body size.[15]
  • Among vertebrates, the Argentine Blue-bill duck has the longest penis in relation to its body size.[16]
  • The vampire squid has the largest eyes of any animal relative to its size.[17]
  • The Kiwi lays the largest egg of any bird relative to its size - up to a quarter of the mass of the female.
  • Shrews have the largest brain-to-body mass ratio of any animal, with brains that are 10% of body weight. Humans however have the largest encephalization quotient of any animal.[18]

Humans[edit]

The Femur is the longest bone in humans

Records[edit]

  • The person with the longest tongue is Steven Taylor of Coventry, England, whose tongue measures 9.8 centimetres (3.86 in).[26]
  • The woman with the longest legs is Svetlana Pankratova. At a height of 200 cm (6.56 ft), her legs measure 132 centimetres (52 in).[27]
  • The woman with the longest fingernails is Lee Redmond. The total length of her fingernails is 7.513 meters.[28]
  • The longest head of hair belonged to Xie Qiuping of China and measured 5.627 metres (18 feet 5.5 inches) on 8 May 2004.[29]
  • The longest beard ever measured belonged to Hans Langseth of Norway; at his death in 1927 it was 5.33 metres (17.5 ft) long.[30][31]
  • The longest ear hair belongs to Victor Anthony of India, measuring 18.1 centimetres (7.12 inches).[32]
  • The largest feet belonged to Matthew McGrory. His left foot measured 17 inches (43 cm) and he wore size 29 1/2 shoes.[citation needed]
