Giraffes have one of the shortest sleep durations among all land mammals, and according to Wildlife FAQ, "On average, adult giraffes sleep for about 30 minutes a night, and their sleep cycles are ...
Giraffes, for example, only need to lie down for REM sleep for a few minutes at a time. Bats sleep while hanging upside down. Male armadillos get erections during non-REM sleep, and the inverse is true in rats. [50] Early mammals engaged in polyphasic sleep, dividing sleep into multiple bouts per day.
[65] [66] However, scientists disagree about just how much time giraffes spend feeding at levels beyond the reach of other browsers, [10] [58] [64] [67] and a 2010 study found that adult giraffes with longer necks actually suffered higher mortality rates under drought conditions than their shorter-necked counterparts. This study suggests that ...
Despite their limited sleep time, giraffes seem to function well and thrive in their natural habitat." Baby giraffes don't sleep a whole lot more than that, they only sleep a few hours a night total.

The okapi's neck is long compared to most ruminants, but not nearly so long as the giraffe's. Male giraffes are the tallest of all mammals: their horns reach 5.5 m (18 ft) above the ground and their shoulder 3.3 m (11 ft), whereas the okapi has a shoulder height of 1.7 m (5 ft 7 in). [9]
The reticulated giraffe (Giraffa reticulata [3] or Giraffa camelopardalis reticulata [4]) is a species/subspecies of giraffe native to the Horn of Africa.It is differentiated from other types of giraffe by its coat, which consists of large, polygonal (or squared), block-like spots, which extend onto the lower legs, tail and face.
Often mistaken with the southern giraffe, the northern giraffe differs by the shape and size of the two distinctive horn-like protuberances known as ossicones on its forehead; they are longer and larger than those of southern giraffe. Male northern giraffes have a third cylindrical ossicone in the center of the head just above the eyes, ranging ...
