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.
The gharial was historically widespread in the major river systems of India but has undergone a chronic decline since 1943. Major threats have included prolific hunting, accidental catching and water blockage from damns. [163] The gharial population continues to be threatened by environmental hazards such as heavy metals and protozoan parasites ...
Gavialoidea is cladistically defined as Gavialis gangeticus (the gharial) and all crocodylians closer to it than to Alligator mississippiensis (the American alligator) or Crocodylus niloticus (the Nile crocodile). [4] [5] This is a stem-based definition for gavialoids, and is more inclusive than the crown group Gavialidae. [6]
The family Gavialidae was proposed by Arthur Adams in 1854 for reptiles with a very long and slender muzzle, webbed feet and nearly equal teeth. [2] It is currently recognized as a crown group, [3] meaning that it only includes the last common ancestor of all extant (living) gavialids (the gharial and false gharial) and their descendants (living or extinct).
The false gharial (Tomistoma schlegelii), also known by the names Malayan gharial, Sunda gharial and tomistoma is a freshwater crocodilian of the family Gavialidae native to Peninsular Malaysia, Borneo, Sumatra and Java. It is listed as Endangered on the IUCN Red List, as the global population is estimated at around 2,500 to 10,000 mature ...
