East African springhare East African springhare The East African springhare ("Pedetes surdaster"), is not closely related to the hare, but is a member of the Pedetidae, a rodent family. "Pedetes surdaster" was recognised by Matthee and Robinson in 1997 as a species distinct from the southern African springhare "(P. capensis)" based on genetic, morphological, and ethological differences. "P. capensis" from South Africa has fewer chromosomes (2n= 38) than does "P. surdaster" which has (2n = 40) and some other genetic variations. The species was confirmed by Dieterlen in 2005. This species is found in central and southern Kenya and most of Tanzania. A
Equator is commonly modeled as a sphere flattened 0.336% along its axis. This makes the Equator 0.16% longer than a meridian (a great circle passing through the two poles). The IUGG standard meridian is, to the nearest millimetre, , one arc-minute of which is , explaining the SI standardization of the nautical mile as , more than less than the geographical mile. The sea-level surface of the Earth (the geoid) is irregular, so the actual length of the Equator is not so easy to determine. "Aviation Week and Space Technology" on 9 October 1961 reported that measurements using the Transit IV-A
