New Guinea crocodile
The New Guinea crocodile (''Crocodylus novaeguineae'') is a small species of crocodile found on the island of New Guinea where there are two geographically isolated populations to the north and south of the mountain ridge that runs along the centre of the island. At one time there were considered to be two subspecies, ''C. n. novaeguineae'', the New Guinea crocodile native to Papua New Guinea, and ''C. n. mindorensis'', the Philippine crocodile but the latter is now considered to be a separate species. The habitat of the New Guinea crocodile is mostly freshwater swamps and lakes. It is most active at night when it feeds on fish and a range of other small animals. A female crocodile lays a clutch of eggs in a nest composed of vegetation and she lies up nearby to guard the nest. There is some degree of parental care for newly hatched juveniles. This crocodile was over-hunted for its valuable skin in the mid 20th century, but conservation measures have since been put in place, it is reared in ranches and the International Union for Conservation of Nature (IUCN) lists it as being of "Least Concern".
==Taxonomy and etymology==
The New Guinea crocodile was first described by the American herpetologist Karl Patterson Schmidt in 1928 as ''Crocodylus novaeguineae''. At one time it was thought that there were two subspecies, ''C. n. novaeguineae'', the New Guinea crocodile native to Papua New Guinea, and ''C. n. mindorensis'', the Philippine crocodile, native to several islands including Busuanga, Luzon, Masbate, Mindoro, Negros, Samar and Mindanao. Most authorities now consider that the Philippine crocodile is an entirely separate species. In fact DNA sequencing data reported in 2011 has shown that the Philippine crocodile is paraphyletic with regard to the New Guinea crocodile, and that the latter constitutes a population within the Philippine crocodile.
The genus name ''Crocodylus'' comes from the Greek ''kroko'' which means a pebble and ''deilos'', a worm or man, referring to the knobbly appearance of the dorsal surface of the reptile. The specific epithet ''novaeguineae'' is from the Latin and means "of New Guinea". Other common names for this crocodile include New Guinea freshwater crocodile, Singapore large grain, Puk Puk, Buaya air tawar and Wahne huala.〔
