Giraffe are thought to have excellent vision. We measured eye size, orbit orientation and retina surface area in 27 giraffes of both sexes ranging in age from neonates to mature adults (>10 yrs), to assess how it changes with growth, whether their eye anatomy correlates with their apparently excellent vision and lifestyle, and we have compared our findings with those for other large mammals to assess whether giraffe eye anatomy is unique. We found that giraffe eye volume increases from 33 cm3… 
Occipital condyle width (OCW) is a highly accurate predictor of body mass in therian mammals
Background Body mass estimation is of paramount importance for paleobiological studies, as body size influences numerous other biological parameters. In mammals, body mass has been traditionally
Giraffes go for more: a quantity discrimination study in giraffes (Giraffa camelopardalis).
The results showed that giraffes can successfully make quantity judgments following Weber's law, can reliably rely on size to maximize their food income, and are more successful when comparing sparser than denser distributions.
Spatial Design of Guest Feeding Programs and Their Effects on Giraffe Participation and Social Interactions.
This study assessed the role of space allocation on giraffe participation and interactions in GFPs in two Florida zoos and proposed the use of multiple guest engagement stations to maximize space and facilitate feeding opportunities for central and peripheral members.


Evolution of eye size and shape in primates.
Retinal cone topography of artiodactyl mammals: Influence of body height and habitat
This study addresses the correlation of retinal topography with factors such as the visual environment, life style, and behavior for a major mammalian group, the artiodactyls, by analyzing topographic maps of 25 species and of the African elephant.

Based on orbit convergence, Primates as a group have the largest binocular visual fields among mammals and display a linear relationship.
Sexual selection is not the origin of long necks in giraffes
It is concluded that morphological differences between males and females are minimal, that differences that do exist can be accounted for by the larger final mass of males and that sexual selection is not the origin of a long neck in giraffes.
A Comparative Assessment of the Size of the Frontal Air Sinus in the Giraffe (Giraffa camelopardalis)
The results suggest that the volume of the frontal sinus in the giraffe is likely to be unique among artiodactyls, and the potential function and evolution is considered in light of several previously articulated hypotheses.
A new look at the scaling of size in mammalian eyes
Over a wide range of body sizes, body mass seems to have no separate and consistent effect on eye/brain ratio, although this ratio is low in many small mammals with poor vision.

Strepsirhine primates have a range of orbit convergence values similar to nocturnal or cathemeral predatory non-primate mammals, consistent with the hypothesis that mammalian predators evolved higher orbit convergence, binocular vision, and stereopsis to counter camouflage in prey inhabiting aNocturnal environment.
Scaling of visual acuity with body size in mammals and birds
Scaling analyses suggest that subjective visual distances for intraspecific social interactions are size dependent, and a positive association between body size and viewing distance has implications for the scaling of coat pattern features.
The allometry and scaling of the size of vertebrate eyes
On the origin, evolution and phylogeny of giraffes Giraffa camelopardalis
It is concluded that the proximate ancestors of modern giraffes probably evolved in southern central Europe about 8 million years ago and may have arisen from the gelocid ancestral assemblage of 20–25 Mya via the family Palaeomerycidae.
