What is another word for myocastor?
Pronunciation: [mˈa͡ɪəkˌastə] (IPA) 
Myocastor is a term commonly used to refer to the coypu or nutria, a semi-aquatic rodent native to South America that has become an invasive species in many parts of the world. Synonyms for myocastor include swamp beaver, river rat, water pig, and nutria rat. These rodents are known for their distinctive orange teeth, webbed hind feet, and round, stocky bodies. They can cause significant damage to wetlands and waterways by eating vegetation and burrowing into banks and levees. Efforts have been made to control populations of myocastor in areas where they are not native, but they continue to thrive in many regions.
