SEA CREATURE
A member of the order
Cetacea, the
blue whale (
Balaenoptera musculus), is thought to be the largest animal ever to have lived. The maximum recorded weight was 190
tonnes for a specimen measuring 30 metres (98 ft), whereas longer ones, up to
33.4 metres (110 ft), have been recorded but not weighed
The
African bush elephant (
Loxodonta africana), of the order
Proboscidea,
is the largest living land animal. A native of various open habitats in
sub-Saharan Africa, this elephant is born commonly weighing about 100
kilograms (220 lb). The largest elephant ever recorded was shot in
Angola
in 1974. It was a male measuring 10.7 metres (35 ft) from trunk to tail
and 4.17 metres (13.7 ft) 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 (13.0 ft).
REPTILE
The largest living reptile, a representative of the order Crocodilia, is the
saltwater crocodile (
Crocodylus porosus)
of Southern Asia and Australia, with adult males being typically
3.9–5.5 m (13–18 ft) long. The largest confirmed saltwater crocodile on
record was 6.3 m (20.7 ft) long, and weighed about 1,360 kg (3,000 lb).
Unconfirmed reports of much larger crocodiles exist, but examinations
of incomplete remains have never suggested a length greater than 7 m
(23 ft).
Also, a living specimen estimated at 7 m (23 ft) and 2,000 kg
(4,400 lb) has been accepted by the Guinness Book of World Records.
However, due to the difficulty of trapping and measuring a very large
living crocodile, the accuracy of these dimensions has yet to be
verified. A specimen named
Lolong caught alive in the Philippines in 2011 (died February 2013) was found to have measured 6.17 m (20.2 ft) in length.
The Komodo dragon (
Varanus komodoensis), also known as the "Komodo monitor", is a large species of lizard found in the
Indonesian islands of
Komodo,
Rinca,
Flores, Gili Motang, and
Padar. A member of the monitor lizard family (Varanidae),
it is the largest living species of lizard, growing to a maximum length
of 3 metres (9.8 feet) in rare cases and weighing up to approximately
70 kilograms (150 pounds).
BIRDS
The largest living bird, a member of the
Struthioniformes, is the common ostrich (
Struthio camelus), from the plains of Africa and Arabia. A large male ostrich can reach a height of 2.8 m (9.2 ft) and weigh over 156 kg (344 lb).
A mass of 200 kg (440 lb) has been cited for the common ostrich but no
wild ostriches of this massive weight have been verified.
Eggs laid by the ostrich can weigh 1.4 kg (3.1 lb) and are the largest eggs in the world today.
The largest bird in the fossil record may be the extinct elephant birds (
Aepyornis) of Madagascar, which were related to the ostrich. They exceeded 3 m (9.8 ft) in height and 500 kg (1,100 lb).
The last of the elephant birds became extinct about 300 years ago. Of
almost exactly the same upper proportions as the largest elephant birds
was
Dromornis stirtoni of
Australia, part of a 26,000-year-old group called mihirungs of the family Dromornithidae.
The largest carnivorous bird was
Brontornis, an extinct flightless bird from South America which reached a weight of 350 to 400 kg (770 to 880 lb) and a height of about 2.8 m (9 ft 2 in).
The tallest carnivorous bird was
Kelenken, which could reach 3 to 3.2 meters in height and 220 to 250 kilograms. The tallest bird ever was the
giant moa (
Dinornis maximus), part of the moa family of New Zealand that went extinct around 1500 AD. This particular species of moa stood up to 3.7 m (12 ft) tall,
but weighed about half as much as a large elephant bird or
mihirung due to its comparatively slender frame.
The largest bird ever capable of flight was
Argentavis magnificens, the largest member of the now extinct
family Teratornithidae,
found in Miocene-aged fossil beds of Argentina, with a wingspan up to
8.3 m (27 ft), a length of up to 3.5 m (11 ft), a height on the ground
of up to 2 m (6.6 ft) and a body weight of at least 80 kg (180 lb).
Pelagornis sandersi is thought to have had a wingspan of comparable size.
