Description
The Orinoco Crocodile ranks among the largest living species of crocodilian and reptile. Typical measurements for males are 3.6-4.8 m (13-16 ft), females are from 3 to 3.3 m (9.9-11 ft). Typical weight for mature females is beetween 225-317 kg (500-700 lbs) and 380-635 kg (837-1400 lbs) for males. The largest specimen reported was shot in 1800, and allegedly measured 6.6 m (22 ft). This was unconfirmed, and modern Orinoco crocodiles have not been reported to exceed 5 m (16.5 ft) in length. It is one of the largest crocodiles in the Americas, and while American Crocodiles and Black Caimans approach similar dimensions, the average weight of the Orinoco Crocodile is slightly higher.
The Orinoco crocodile can be recognised by its relatively long snout, which is narrower than the somewhat similar-looking American crocodile's. This species generally has a pale tan hide, though at least three coloration variations are known, with some almost completely yellowish and some a dark brownish-gray. It has been noted that the skin can change colour over long periods of time; this phenomenon has been recorded in other species that can gradually change the amount of melanin in their skin. These crocodiles have dark brown markings, which present as more pronounced bands in younger specimens and as scattered markings on mature ones.

Famous quotes containing the word description:
“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (18171862)
“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the childs stage in life has become an indictment, a judgment.”
—Elaine Heffner (20th century)
“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeares description of the sea-floor.”
—Henry David Thoreau (18171862)
