026. ‘MAKING A SPLASH’. Hippos. Nsefu Sector, South Luangwa National Park, Zambia
The name ‘Hippopotamus’ comes from the Greek for ‘river horse’. After elephant and rhinoceros, it is the third largest mammal. The hippo is territorial in water only. A bull presides over a certain stretch of river containing about ten females. Yawning serves as a threat display. When fighting, males use their incisors to block attacks.
