Vervet monkey, text around, date below.

The vervet monkey (Chlorocebus pygerythrus), or simply vervet, is an Old World monkey native to Africa. These mostly herbivorous monkeys have black faces and grey body hair color, ranging in length from about 50 centimetres (20 in) for males to about 40 centimetres (16 in) for females.
In addition to behavioral research on natural populations, vervet monkeys serve as a nonhuman primate model for understanding genetic and social behaviors of humans. They have been noted for having human-like characteristics, such as hypertension, anxiety, and social and dependent alcohol use. Vervets live in social groups ranging from 10 to 70 individuals.
