Something About Primates
PRIMATES share many characteristics with other animals, but they differentiate as a distinct group from other mammals with certain special features. On a CLASSIFICATION chart, a chart that organizes diversity into categories and indicates evolutionary relationships, primates are categorized under the Phylum CHORDATA, containing all VERTEBRATES (animals with segmented spinal columns), and are also split into 2 suborders: HAPLORHINI, which includes lemurs and lorises and STREPSIRHINI, which includes tarsiers, monkeys, apes, and humans. I went to the Santa Barbara Zoo and observed their primates. I looked at 2 apes: the western lowland gorilla and the white-handed gibbon and 1 monkey: the Bolivian grey titi monkey.

Along with walking around, I observed that the gorillas’ diet was OMNIVOROUS, eating plants and insects. The way they foraged was simply by picking the grass and insects from the ground with their fingers. There were two males in the exhibit and their BEHAVIOR, actions or responses to any internal or external forces, were similar and performed together instead of separately and on their own.

They can just be friendly without the fighting over a mate. They might have been lazy because of their environment.
