Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Visual preference was evaluated in a male agile gibbon.

A high level of plasticity was found in great calls from the same individual, and generally the inferred pattern of variability suggested that ecological or social factors may confound any genetically based island dialects.

Demographic processes place gibbons at risk, however, to short-term changes in their environment. Additionally, the male is slightly larger than the female.

The group usually consists of the male and female mated pair, an infant, and a juvenile. Patterns of survival, fecundity, mortality, and dispersal combined to produce negative rates of growth. Other Physical Features endothermic homoiothermic bilateral symmetry Sexual Dimorphism male larger Range mass 4 to 6 kg 8. With set 1, the subject touched photographs of humans more frequently than those of other hyloates, recalling previous findings in human-reared chimpanzees.
