[64] [65] However, scientists disagree about just how much time giraffes spend feeding at levels beyond the reach of other browsers, [10] [57] [63] [66] 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 ...
To understand why giraffes fight we need to take a look at their social hierarchy. Giraffes live in stable family groups with older females helping the mothers to care for the young. A group of ...
A Penn State researcher has been trying to get to the bottom of the age-old question of why giraffes have long necks. Focus on research: Female giraffes drove the evolution of long necks, new ...
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 neck adaptations of Discokeryx help scientists to better understand the triggers for the evolution of the necks of giraffoids. [ 1 ] [ 3 ] Compared to extant head-butting animals such as rams and musk-oxen, D. xiezhi had the most optimized head-butting adaptations of all, with a skull that protected the brain more efficiently than other ...

The gerenuk has a longer, heavier neck and a shorter tail. [10] A finer point of difference is the absence of an inward-curving lobe in the lower edge of the ear (near its tip) in the gerenuk. [ 15 ] The subspecies of the gerenuk are similar in colouration; the southern gerenuk is the smaller of the two. [ 10 ]
Tails of many extant lizards (geckos, chameleons, and a species of skink) are prehensile; Seahorses grip seaweed with their tails. Several fossil animals have been interpreted as having prehensile tails, including several Late Triassic drepanosaurs, [2] and possibly the Late Permian synapsid Suminia.
