false gharial
The false gharial (''Tomistoma schlegelii''), also known as the Malayan gharial and Sunda gharial or (due to its scientific name) the Tomistoma, is a freshwater crocodilian with a very thin and elongated snout. It is listed as "Vulnerable" by the IUCN, as the population is estimated at less than 2,500 mature individuals.
== Taxonomy ==
Unlike the gharial, the false gharial's snout broadens considerably towards the base and so is considerably more similar to those of true crocodiles than the gharial, whose osteology indicates a distinct lineage from all other living crocodilians.〔 However, preliminary nuclear genetic sequences may indicate the gharial and false gharial had a shared ancestor at some point in prehistory.〔Willis, R. E., McAliley, L. R., Neeley, E. D., & Densmore, L. D. (2007). ''Evidence for placing the false gharial (Tomistoma schlegelii) into the family Gavialidae: inferences from nuclear gene sequences''. Molecular phylogenetics and evolution, 43(3), 787-794.〕 Other molecular studies have similarly indicated that it is the nearest relative (the sister taxon) of the gharial. Along with close fossil relatives, such as ''Maroccosuchus'', it is thus increasingly classed in the family Gavialidae.
