the Crocodile breathes air just like we do, but he is very well adapted
to life in the water. When he opens his mouth underwater a special
flap of skin at the back of his throat stops the water entering his
gullet. He has an unusual heart with 4 chambers, and when he dives
blood with oxygen is sent to his brain while blood without much
oxygen goes through the rest of his body. This way he can use his
oxygen very well and stay under water longer.
Eventually Crikey must
rest to replenish his oxygen. He
spends a lot of time regulating his body temperature. When he needs
heat he will bask in the sun, and when he gets too hot he will find
some shade or lie in shallow water.
have 66 teeth. When they lose one, another is waiting to take its
place. Their jaws are very strong and close with tremendous force.
Salt Water crocodiles may grow to five or six metres in length, with
an occasional really big one almost seven metres in length and as
heavy as ten men.
swim with their tails, but they also have webbing between three of
their back toes. They have excellent hearing and with eyes like a
cat's, they see very well at night.
crocodiles may lay up to sixty eggs in a nest of vegetation near the
water's edge. She guards the nest and when the hatchlings emerge she
will carry them in her mouth to the water and stay with them for a
few months. Incubation at 30 degrees centigrade or less produces female
young, 31 degrees produces both sexes, while 32-33 degrees produces
male young. Of 1000 eggs laid, only about 8 crocodiles will live to
be over 5 years old.
