Definition
'Megalonychidae' is the scientific family name for two-toed sloths. It's how scientists classify these slow-moving mammals. Think of it like the last name for all two-toed sloths. It distinguishes them from three-toed sloths (Bradypodidae). They are known for their deliberate movements and arboreal lifestyle. They are found in Central and South America. This reflects their evolutionary relationships.
