Like water off a buck’s back:
Waterbucks have numerous glands that secrete an oily substance, coating the fur and making it waterproof – perfect for life in wet habitats.

Maternity leave:
After birth, baby waterbucks stay hidden in the tall, protective grasses for around four weeks before mother and child re-join the herd. The calves stay with their mothers for around 9 months.

  • only male waterbucks have horns,
    • the females live with the young in nursery herds and the males stay in bachelor herds,

      • and male waterbucks don’t reach sexual maturity until 6 years old, while the females are fertile by the age of 3?
