average of 1.5 m (5 ft). human-populated areas.
7. Chinese Alligator
There are a few differences.
One obvious difference is that
the Chinese alligator is quite
small. Usually only attaining a
length of 5 feet
(1.5 m), these alligators are
known to grow to 7 feet
(2.1 m). Unlike the American
alligator, the Chinese alligator
is fully armored; even the
belly is armored, which is a
feature of only a few
crocodilians. They weigh up to
100 pounds (45 kg). Chinese
alligators grow slowly, being
only 2 ft (60 cm) long after 2
years of age.
8. American Alligator
They could survive only in
captivity. Like all albino
animals, they are very
vulnerable to the sun and
predators.American Alligators
can remain underwater for
several hours if not actively
swimming or hunting (then it
is only about 20 minutes);
they do this by rerouting
blood to reduce circulation to
the lungs, and thus the need
for oxygen.
12. Black Caiman
It is the largest predator in
the Amazon basin and
possibly the largest member
of the family Alligatoridae.
Most adult black caimans are
3 to 4.26 metres (9.8–14 ft)
in lengths, with old males
rarely growing larger than 5
metres (16 ft). In some areas
(such as the Araguaia River)
this species is consistently
reported at 4 to 5 metres
(13–16 ft) in length, much
larger than the alligator
(which rarely even reaches 4
meters). Several unconfirmed
sources report that the black
caiman can grow to 6 metres
(20 ft) or more.
13. Orinoco Crocodile
Typical measurements for adults
range from 3 to 4.8 m (9.9-16
ft). Typical weight for mature
females is 200 kg (440 lbs) and
380 kg (837 lbs) for males. The
largest specimen reported was
shot in 1800 and allegedly
measured 6.6 m (22 ft). Even at

Orinoco River drainage basin and
the Meta River drainage basin in
Colombia and Venezuela. Young

14. African Slender-
snouted Crocodile
These crocodiles are not
endangered.
African Slender-snouted
Crocodile begin to breed in
the rainy season. The female
constructs a mound nest
consisting mainly of plant
matter, which is sited usually
on river banks. The eggs have
a long incubation
period, sometimes up to 110
days.
15. Philippine crocodile
The Philippine crocodile is
only found on the islands of
the Philippines. This species
of crocodile is one of the most
severely threatened species
around. There are roughly
250 left in the wild as of
September 2011 according to
an article with National
Geographic.
The Philippine crocodile has
been extirpated in
Samar, Jolo, Negros
Island, Masbate, and
Busuanga. There are still
surviving population in the
Northern Sierra Madre
National Park, San
Mariano, Isabela, Dalupiri
island in the Babuyan
Islands, and Abra (province)
in Luzon and Ligawasan
Marsh in Mindanao.]
16. Nile Crocodile
In antiquity, Nile crocodiles
occurred in the Nile delta and
the Zarqa River. They are
recorded by Herodotus to
have inhabited Lake Moeris.
The Nile crocodile's range of
distribution extends from the
Senegal River, Lake Chad,
Wadai and the Sudan to the
Cunene and the Okavango
Delta. many In East Africa,
they are found mostly in
rivers, lakes, marshes, and
dams. They have been known
to enter the sea , with one
specimen having been seen
11 km off St Lucia Bay in
1917.
17. Dwarf Crocodile
Dwarf crocodiles range across
tropical lowland regions of
sub-Saharan West Africa and
West Central Africa. Such a
distribution greatly overlaps
with that of the slender-
snouted
crocodile, encompassing
countries as far West as
Senegal, reaching the Central
African Republic in the
East, and ranging as
southerly as Angola. The
subspecies O. t. tetraspis is
found mainly in the westerly
reaches of this range while O.
t. osborni is restricted to the
Democratic Republic of
Congo's rain forest.
