Crocodiles
Crocodiles (family Crocodylidae) or true crocodiles are large semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. The term crocodile is sometimes used even more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (family Alligatoridae), the gharial and false gharial (family Gavialidae) among other extinct taxa. Although they appear similar, crocodiles, alligators and the gharial belong to separate biological families. The gharial, with its narrow snout, is easier to distinguish, while morphological differences are more difficult to spot in crocodiles and alligators. The most obvious external differences are visible in the head, with crocodiles having narrower and longer heads, with a more V-shaped than a U-shaped snout compared to alligators and caimans. Another obvious trait is that the upper and lower jaws of the crocodiles are the same width, and the teeth in the lower jaw ...

American Crocodile
The American crocodile (''Crocodylus acutus'') is a species of crocodilian found in the Neotropics. It is the most widespread of the four extant species of crocodiles from the Americas, with populations present from South Florida and the coasts of Mexico to as far south as Peru and Venezuela. The habitat of the American crocodile consists largely of coastal areas. It is also found in river systems, but tends to prefer salinity, resulting in the species congregating in brackish lakes, mangrove swamps, lagoons, cays, and small islands. Other crocodiles also have tolerance to saltwater due to salt glands underneath the tongue, but the American crocodile is the only species other than the saltwater crocodile to commonly live and thrive in saltwater. They can be found on beaches and small island formations without any freshwater source, such as many cays and islets across the Caribbean. They are also found in hypersaline lakes; one of the largest known populations inhabits Lago Enriq ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mugger Crocodile
The mugger crocodile (''Crocodylus palustris'') is a medium-sized broad- snouted crocodile, also known as mugger and marsh crocodile. It is native to freshwater habitats from southern Iran to the Indian subcontinent, where it inhabits marshes, lakes, rivers and artificial ponds. It rarely reaches a body length of and is a powerful swimmer, but also walks on land in search of suitable waterbodies during the hot season. Both young and adult mugger crocodiles dig burrows to which they retreat when the ambient temperature drops below or exceeds . Females dig holes in the sand as nesting sites and lay up to 46 eggs during the dry season. The sex of hatchlings depends on temperature during incubation. Both parents protect the young for up to one year. They feed on insects, and adults prey on fish, reptiles, birds and mammals. The mugger crocodile evolved at least and has been a symbol for the fructifying and destructive powers of the rivers since the Vedic period. It was first sc ...

Orinoco Crocodile
The Orinoco crocodile (''Crocodylus intermedius'') is a critically endangered crocodile. Its population is very small, and they can only be found in the Orinoco river basin in Colombia and Venezuela. Extensively hunted for their skins in the 19th and 20th centuries, it is one of the most endangered species of crocodiles. It is a very large species of crocodilian; males have been reported up to in the past, but such sizes do not exist today, being a more widely accepted maximum size. A large male today may attain in length and can weigh up to , while females are substantially smaller with the largest likely to weigh around . Sexual dimorphism is not as profound as in other crocodilian species. The coloration is light even in adults. The biology of the Orinoco crocodile is poorly documented in the wild, mostly due its small population. It is thought to have a more piscivorous diet with an opportunistic nature, resulting in generalist predatory behavior. The Orinoco crocodile is ...

Freshwater Crocodile
The freshwater crocodile (''Crocodylus johnstoni''), also known as the Australian freshwater crocodile, Johnstone's crocodile or the freshie, is a species of crocodile endemic to the northern regions of Australia. Unlike their much larger Australian relative, the saltwater crocodile, freshwater crocodiles are not known as man-eaters, although they bite in self-defence, and brief, nonfatal attacks have occurred, apparently the result of mistaken identity. Taxonomy and etymology When Gerard Krefft named the species in 1873, he intended to commemorate the man who first reported it to him, Australian native police officer and amateur naturalist Robert Arthur Johnstone (1843–1905). However, Krefft made an error in writing the name, and for many years, the species has been known as ''C. johnsoni''. Recent studies of Krefft's papers have determined the correct spelling of the name, and much of the literature has been updated to the correct usage, but both versions still exist. Accor ...

Philippine Crocodile
The Philippine crocodile (''Crocodylus mindorensis''), also known as the Mindoro crocodile, the Philippine freshwater crocodile, the ''bukarot'' in Ilocano, and more generally as a ''buwaya'' in most Filipino lowland cultures, is one of two species of crocodiles found in the Philippines; the other is the larger saltwater crocodile ''(Crocodylus porosus)''. The Philippine crocodile, the species endemic only to the country, went from data deficient to critically endangered in 2008 from exploitation and unsustainable fishing methods, such as dynamite fishing. Conservation methods are being taken by the Dutch/Filipino Mabuwaya foundation,"Philippine Crocodile Comeback" . cepf.net.

Crocodylus Halli
''Crocodylus halli'', also known as Hall's New Guinea crocodile, is a species of crocodile endemic to the island of New Guinea. It is found on the southern half of the island, south of the New Guinea highlands. It is named after Philip M. Hall, a researcher at the University of Florida who performed the initial studies to clarify the species' distinctiveness. Taxonomy The species was formerly considered a distinct population of the closely related New Guinea crocodile (''C. novaeguineae''), but genetic analysis as well as morphological analysis of its skull structure (namely the postcrania and maxilla) has supported it being classified as its own species. The two species likely diverged within the last 3-8 million years, when the uplift of the New Guinea highlands created a barrier that divided them into separate populations. Despite the common ancestry of the two species, genetic analysis indicates that the New Guinea crocodile may be more closely related to the putative Born ...

Gerard Krefft
Johann Ludwig (Louis) Gerard Krefft (17 February 1830 – 19 February 1881), a talented artist and draughtsman, and the Curator of the Australian Museum for 13 years (1861-1874), was one of Australia's first and most influential zoologists and palaeontologists. According to Macdonald, et al. (2007), Krefft "was among the first to raise the alarm" in relation to "the devastating effects" of the invasive species, such as "sheep, cats, etc., on native species". Also, along with significant others, such as the proprietor of the Melbourne ''Argus'', Edward Wilson, Krefft expressed considerable concern in relation to the effects of the expanding European settlement upon the indigenous population. In addition to his numerous scientific papers, his publications include ''The Snakes of Australia'' (1869), ''Guide to the Australian Fossil Remains in the Australian Museum'' (1870), ''The Mammals of Australia'' (1871), and ''Catalogue of the Minerals and Rocks in the Australian Museum' ...
