Where
seen? This awesome reptile is sometimes seen at Sungei
Buloh Wetland Reserve.
According to Davison, it has been recorded in our estuaries and reservoirs
including the Singapore River, Kallang River, Sungei Seletar and Kranji
Reservoir, and Pulau Tekong. Also called the Saltwater crocodile,
it is the most widely distributed of the crocodiles and found in tropical
Asia and the Pacific. It lives in brackish and freshwater habitats.
Features: Up to 8m long.
A large triangular head with broad and long snout and bulbous eyes
at the top of the head. There is a pair of ridges along the centre
of the snout. It uses its long muscular tail to propel itself in the
water. Younger crocodiles have oval scales that are pale yellow with
black stripes and spots on the body and tail. The adults are much
darker, with lighter tan or grey areas.
What does it eat? Juveniles eat
insects, frogs, crabs and fishes. Adults eat larger prey including
fish, birds and mammals, hunting mainly at night. They may also scavange
on carrion.
Crocodile babies: A mother crocodile
specially constructs a nest of vegetation in which about 80 eggs are
laid. The warmth of the decomposing vegetation incubates the eggs.
The mother fiercely guards the nest.
Status and threats: Our Estuarine
crocodiles are listed as 'Critically Endangered' in the Red List of
threatened animals of Singapore.

| They are
threatened by habitat loss and human persecution. Also considered
threatened globally, although successful captive breeding has
reduced hunting pressure on wild populations. They are hunted
for their skin which is used to make leather goods such as shoes
and handbags. Their meat is also eaten. |
