The SirenJaw is a colossal crocodilian predator indigenous to the lakes and tributaries of the southern jungle. It's hybrid physiology exhibits some of the most extreme examples of florafauna yet seen. As it matures, the SirenJaws goes through a pubescent stage in which a small nursery of deciduous trees grows across it's rocky back, making it an integrated biological chapter of the jungle region in which it has thrived. True to its name, the exotic plant life and rock life structures growing above the creature's submerged body prove too alluring to resist for the unsuspecting prey of the Siren. Any living thing that strays upon this "shore" is fainted to discover that some islands have teeth.
