Sometimes, specialization in nature results from evolutionary pressure or a new niche becoming available. The unique gavials of India possess an astoundingly long, needlelike snout and multitudes of sharp teeth. Gavials have never been responsible for any human casualties, as their bite is extremely weak, and their demeanor is far less aggressive than the typical hunting crocodilian. Gavials may appear to be extremely creepy, or even comical at times. Unfortunately, the animals are highly endangered as a result of preventable causes, including poaching, siltation, and water contamination.
