1. How does courship behaviour work?

  • Recognise the opposite sex only
  • Allow species to recognise each other, stimulate the release of gametes, recognise the opposite sex, indicate sexual maturity
  • Recognise the same species, stimulate release of gametes, kill predators, indicate sexual maturity
