The giant panda (Ailuropoda melanoleuca) (

is

a

mammal

classified

in

the

bear

family,

Ursidae,

native

to

central-western

and southwestern China. It is easily recognized by its large, distinctive

black

patches

around

the

eyes,

ears

and

on

its

rotund

body.

Though

technically

a

carnivore,

the

panda

has

a

diet

which

is

98%

bamboo.

However,

they

may

eat

other foods such as honey, eggs, fish, and yams.

The

Giant

Panda

is

an

endangered

animal;

an

estimated

3,000

pandas

live

in the wild and over 180 were reported to live in captivity by August 2006

in

mainland

China

(another

source

by

the

end

of

2006

put

the

figure

for

China

at

221),

with

twenty

pandas

living

outside

of

China.[citation

However,

reports show that the numbers of wild panda are on the rise.

The giant panda has long been a favorite of the public, at least partly

on account of the fact

that the species

has an

appealing baby-like cuteness

that

makes

it

seem

to

resemble

a

living

teddy

bear.

The

fact

that

it

is

usually

depicted

reclining

peacefully

eating

bamboo,

as

opposed

to

hunting,

also

adds

to its image of innocence. Though the giant panda is often assumed docile

because of their cuteness, they have been known to attack humans, usually

assumed to be out of irritation rather than predatory behavior.

The Giant Panda has a very distinctive black-and-white coat. Adults

measure around 1.5 m long and around 75 cm tall at the shoulder. Males can

weigh up to 115 kg (253 pounds). Females are generally smaller than males,

and can occasionally weigh up to 100 kg (220 pounds). Giant Pandas live in

mountainous regions, such as Sichuan, Gansu, Shaanxi, and Tibet. While the

Chinese

dragon

has

been

historically

a

national

emblem

for

China,

since

the

latter half of the 20th century the Giant Panda has also become an informal

national emblem for China. Its image appears on a large number of modern

Chinese commemorative silver, gold, and platinum coins.

The

Giant

Panda

has

an

unusual

paw,

with

a

and

five

fingers;

the

a

modified

sesamoid bone,

which helps the

panda to

hold

the bamboo while eating. Stephen Jay Gould wrote an essay about this, then

used

the

title

The

Panda's

Thumb

for

a

book

of

essays

concerned

with

evolution

and intelligent design. The Giant Panda has a short tail, approximately 15

cm long. Giant Pandas can usually live to be 20-30 years old while living

in captivity.

Until

recently,

scientists

thought

giant

pandas

spent

most

of

their

lives

alone,

with

males

and

females

meeting

only

during

the

breeding

season.

Recent

studies paint a different picture, in which small groups of pandas share a

large territory and sometimes meet outside the breeding season.[citation

Like most subtropical mammals, but unlike most bears, the giant panda

does not hibernate.

National

Zoo

Washington,

e

classification

as

a

the

has

a

diet

that

herbivorous,

This

is

an

evolutionarily

recent

adaptation.

Pandas

lack

the

proper

enzymes

to

digest

bamboo efficiently, and thus derive little energy and little protein from

it.

While primarily herbivorous, the panda still retains decidedly ursine

teeth,

and will

eat meat,

fish, and eggs

when available.
