This might be the first ever recorded rescue of a baby wildebeest and a baby zebra by the same hippo on the Mara River (Serengeti NP) in Tanzania. Both foals were rescued within 10 min as they were trying to cross the raging river.
The hippo was watching as the wildebeest herd swam past. As soon as the calf jumped in, the hippo swam up to it and pushed it along all the way across until it had reached safety on the other side. It then went back and did the same for a zebra foal just minutes later.
