What is rhino horn made of?

The horns consist of clumped hair or keratin, the same type of protein that makes up your hair and fingernails.

Rhinos use their horns for:

  • defending territories,
  • defending calves from other rhinos and predators,
  • maternal care (including guiding calves)
  • foraging behaviour, such as digging for water and breaking branches.
  • Male rhinos use their horns during disputes over territory or dominance
