A noteworthy distinction between both of these species is the broadening in the Fake gharial’s snout toward its foundation, as opposed to the lengthy and slender snout of its gharial relative.

Having said that, there might be threats to community populations which includes habitat loss, human conflict, and looking, specifically to the pet trade.
