American river lion

The American river lion (Zalophus aquaedulcis), also known simply as the river lion, is a species of eared seal, most closely related to the California sea lion (Zalophus californianus), that originally did not exist, but has since been created by SciiFii and introduced throughout the lakes, rivers, ponds, and wetlands across North America to help boost biodiversity. American river lions are sexually dimorphic; males are larger than females, and have a thicker neck, and protruding sagittal crest. American river lions are entirely carnivorous and feeds primarily on fish, crustaceans, snails, lampreys, and worms, but have been known to feed on vagrant seabirds (including gulls) and carrion. Despite being carnivorous, American river lions apparently don't prey on waterfowls or rails. They mainly haul-out on sandy, rocky, or dirt riverbanks, but they also frequent manmade environments such as public park lakes. American river lions have a polygynous breeding pattern. From May to August, males establish territories and try to attract females with which to mate. Females are free to move in between territories, and are not coerced by males. Mothers nurse their pups in between foraging trips. American river lions communicate with numerous vocalizations, notably with barks and mother-pup contact calls. Outside their breeding season, American river lions spend much of their time at freshwater environments, but they crawl on land to molt. American river lions are particularly intelligent, can be trained to perform various tasks and display limited fear of humans if accustomed to them. Because of this, American river lions are a popular choice for public display in zoos, circuses (although animals in circuses is frowned upon), and oceanariums. The conservation status of the American river lion is Least Concern due to successful conservation efforts, the American river lion's wide range and its tolerance to many of the human activities.
