What is the cleverest thing a hippo can do?鈥� Elliot, 8, England
The cleverest thing a hippo can do? Woah, I can鈥檛 wait to hear how this one gets answered! We turned to Keenan Stears of the University of California Santa Barbara for some help with this tricky query.
鈥淭he first thing that comes to mind that highlights the intelligence of hippos is the ability to identify hippo friends from hippo enemies by the smell of their dung,鈥� he said.
Dung is a word for poop.
鈥淒ominant male hippos use dung middens to mark their territories. A dung midden is a place where an animal repeatedly goes to drop their dung. The dung middens act as a way that hippos can keep track of the other hippos in the area. So when moving through the environment, hippos can sniff out areas where their hippo friends live, versus areas where their hippo enemies live and they can do all of this just by smelling the dung in middens.鈥�
Bet you didn鈥檛 think the cleverest thing hippos can do might involve poop. And just in case it wasn鈥檛 totally clear, a midden is basically a waste pile. So a dung midden is kind of like a toilet or an outhouse. It鈥檚 where the hippos go repeatedly to poop. But, as Stears told us, it also serves another purpose. While humans can鈥檛 tell their poop from someone else鈥檚, other animals can sniff out individuals this way, and use dung or urine鈥攑ee鈥攖o mark their territories.
Hippos aren鈥檛 the only animals to use dung middens this way, by the way. Rhinoceroses do this too! Other animals, like dogs, cats, bunnies and monkeys also sniff feces and urine as a way to learn about their fellow species, but they don鈥檛 always leave their 鈥渕essages鈥� in the same place.
