    5. 5. Chinese AlligatorThere are a few differences.One obvious difference is thatthe Chinese alligator is quitesmall. Usually only attaining alength of 5 feet (1.5 m),these alligators are known togrow to 7 feet (2.1 m).

Like all albinoanimals, they are veryvulnerable to the sun andpredators.American Alligatorscan remain underwater forseveral hours if not activelyswimming or hunting (then itis only about 20 minutes);they do this by reroutingblood to reduce circulation tothe lungs, and thus the needfor oxygen.
    7. 7. Predators babies: raccoons, otters, herons, snakes, snapping turtles, other alligators, Humans
    8. 8. Crocodiles
    9. 9. Black CaimanIt is the largest predator inthe Amazon basin andpossibly the largest memberof the family Alligatoridae.Most adult black caimans are3 to 4.26 metres (9.8–14 ft)in lengths, with old malesrarely growing larger than 5metres (16 ft). In some areas(such as the Araguaia River)this species is consistentlyreported at 4 to 5 metres(13–16 ft) in length, muchlarger than the alligator(which rarely even reaches 4meters). Several unconfirmedsources report that the blackcaiman can grow to 6 metres(20 ft) or more.
    10. 10. Orinoco CrocodileTypical measurements for adultsrange from 3 to 4.8 m (9.9-16ft). Typical weight for maturefemales is 200 kg (440 lbs) and380 kg (837 lbs) for males. Thelargest specimen reported wasshot in 1800 and allegedlymeasured 6.6 m (22 ft). Even atits, although It is restricted to theOrinoco River drainage basin andthe Meta River drainage basin inColombia and Venezuela.
