Blesboks typically live from 17 years and 3 months to 28 years and 9 months, with a maximum lifespan of 23 years; the species reaches sexual maturity from 1 year and 7 months to 4 years. The embryo develops inside the mother and receives nourishment from her. At birth, the young’s eyes open, and it begins to walk. The young feeds on its mother's milk and gradually starts eating grass during the infant stage, which lasts from 1 day to 6 months. The adult stage begins at 2 years and continues for 20 years, during which the blesbok is capable of reproduction and lives in a herd.

Bontboks inhabit land, preferring terrestrial grasslands and steppes, as well as grassy areas and plains, being found up to an altitude above sea level of 2 km. The species populates tropical savanna where the climate is characterized by heat and uneven rainfall, as well as temperate steppe with an abundance of grass and few trees. Bontboks are found in hot steppe with a very hot summer and drought, in zones with a very dry climate where rains are extremely rare, and in areas that are dry and cold almost all year. Climatic conditions of their habitat include little precipitation in winter and their increase in summer, as well as periods when it is very hot and there is practically no precipitation.

The blesbok, also known as bontebok or sassaby, reproduces through live birth on land, without eggs or larvae. The female carries a single offspring for about eight months during gestation; she gives birth to one young after this period. Newborns conceal themselves in grass. The species reaches maturity from 2 years to 3 years and 4 months. The female produces offspring at an interval of 11 months to 2 years, with each litter containing only one individual. Eggs, larvae, or young are laid directly on the ground without shelter. Reproduction always involves fertilization, but does not involve alternation of generations.
