Hippos are not typically considered the most energetic of animals. But when one of their own is in danger you can be sure that their protective instincts will kick in.
A new video has emerged of a herd of hippos bandying together in the Serengeti to take down a crocodile threatening attack on its young.
The group of more than 30 hippos are seen piling on the crocodile and holding it underwater while two baby hippos are sheltered in the background.
When the crocodile re-emerges from the water next to the two babies, one of the adults is then quick to capture it in its teeth and tackle it down.
Harish Kumar, a 71-year-old retired sonographer, who recorded the footage said the babies were saved but the crocodile later swam away unharmed.
He recalled to Latestsightings.com how he was traveling with a tour group when the incident unfolded.
