Lurker/biology

It was an amphibian that had grown to large proportions. Its eyes had devolved greatly from the mutation, but this was compensated with improved hearing senses and a strong body that was almost impervious to bullets, yet significantly weak to knifing attacks. They attacked with sharp piercing tongues that could actually impale a human target with little effort and could swallow a human body whole due to their well-developed digestive system.
