BEHAVIOR

  • Mostly solitary, although this species is the most social and will form small groups of both sexes and all ages occasionally.
  • Dependent on small pools of water for drinking and will visit pools daily when they are readily available. Rhinos also depend on mud to coat their skin. It is thought to help protect against biting flies.

  • Females will stand protectively over their young if danger is present. White rhinos are not as aggressive as black rhinos and are frightened off easily.
