what family do Kiwi and the common ostrich belong to?
Kiwi Kiwi (pronounced ) or kiwis are flightless birds native to New Zealand, in the genus Apteryx and family Apterygidae. Approximately the size of a domestic chicken, kiwi are by far the smallest living ratites (which also consist of ostriches, emus, rheas, and cassowaries), and lay the largest egg in relation to their body size of any species of bird in the world.
Sloth Sloths are mammals classified in the families Megalonychidae (two-toed sloths) and Bradypodidae (three-toed sloths). There are six extant species of sloths. They are named after the capital sin of sloth because they seem slow and lazy at first glance; however, their usual idleness is due to metabolic adaptations for conserving energy. Aside from their surprising bursts of speed during emergency flights from predators, other notable traits of sloths include their strong body, the ability to swim, and the fact that they host symbiotic algae on their fur.
