The Ruurin is a medium sized monster of the Leviathan species that first appears in the fan - made game Monster Hunter Z. They are related to the carnivorous Kharasoron.


Ruurin have small horns protruding from the top of their head, and long, bat - like ears that have fins on the edges. They have long, slender snouts and narrow, needle - like teeth that they use for grasping slippery fish. They have white scales that reflect light and make them appear luminous. Above their backs are tall rods of bone supporting a stretch of skin, forming some sort of sail. They have fins instead of front legs, and their hind legs have webbed toes. Their tail possesses distinctive spikes that they swing around at predators or hunters trying to attack them. They also have a purple sac underneath their throats, which is used to store sea water. They can then spit the stored sea water out as a water ball when defending themselves.


Ruurin have completely adapted to life underwater, evolving fins, webbed feet, and even gills (in adulthood), allowing them to escape the vulnerability of having to resurface for air, staying safe beneath huge underwater rock formations where lots of Fish gather, which they prey on. Females will only leave the sea to lay their eggs on the seashore; baby Ruurins do not have gills yet and their lungs will develop into gills when they are about 3 or 4 weeks old. Laying eggs is a dangerous game for the mothers, as they have to hold their breath for as long as they can, as they lay about 50 - 100 eggs underneath the sand. Most mothers cannot hold their breath for that long and die as they lay their eggs. After hatching under the sand, the babies will make a mad dash to the sea and spend the rest of their lives underwater. During the first few weeks of their life, they must find thick kelp to live in, which is safe from predators, and will allow them easy access to the surface for a breath of air. The small fish which come into the kelp for protection is their prey. After maturing and developing gills, or simply if they have become too large, they will leave the kelp and find other Ruurin to hunt and mate with. They hunt in packs of 3 or 4, using their numbers to herd schools of fish and to outmanoeuvre predators. 


Ruurin are only found underwater, usually around huge underwater rock formations or coral, which is teeming if life, mostly fish, which they hunt for food. Occasionally, dead female Ruurins will be found on the seashore over their eggs.
