Sylvilagus aquaticus, commonly known as the swamp rabbit, is a species of cottontail rabbit that is typically found in the southeastern United States. It's a unique rabbit, adapted to living in wetlands and swamps, with significantly longer legs and webbed toes compared to other cottontails. However, if you're looking for synonyms of the scientific name, you could use the term "water-loving cottontail" or "swamp-dwelling rabbit." "Sylvilagus" itself is a genus of cottontails, with over 20 different species, and "aquaticus" referring to its affinity for water. Other synonyms could include "marsh rabbit," "swamp hare," or simply "water rabbit".
