Animals with only two limbs

Moa (order Dinornithiformes) are an extinct group of flightless birds formerly endemic to New Zealand. During the Late Pleistocene-Holocene, there were nine species, in six genera. The two largest species, Dinornis robustus and Dinornis novaezelandiae, reached about in height with neck outstretched, and weighed about ; the smallest, the bush moa (Anomalopteryx didiformis), was about the size of a turkey. Estimates of the moa population when Polynesians settled New Zealand circa 1300 C.E. range from 58,000 to 2.5 million.
