What's the Cleverest Thing A Hippo Can Do?
What is the cleverest thing hippos can do? This week we\u2019re answering seven quirky questions about animals! Why do elephants like peanuts? Why do cows put their tongues up their noses? Has anyone ever ridden a tiger? How do woodpeckers cling to trees? Why is some bird poop black and some is white? Why do people make animals like sharks and bears sound way scarier than they are? Answers from Keenan Stears of the University of California, Santa Barbara, Christine Scales of Billings Farm & Museum; shark researcher Kady Lyons and the Bird Diva Bridget Butler.

\n\n\n\n\nWhat is the cleverest thing a hippo can do? \u2013 Elliot, 8, England

\nWe turned to Keenan Stears of the University of California, Santa Barbara for some help with this tricky query.
\u201cThe first thing that comes to mind that highlights the intelligence of hippos,\u201d he told us, \u201cis the ability to identify hippo friends from hippo enemies by the smell of their dung.\u201d Dung is another word for poop.
\n\n\u201cDominant 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.\u201d
\n\nBet you didn\u2019t think the cleverest thing hippos can do would involve poop! And just in case it wasn\u2019t totally clear, a midden is basically a waste pile. So a dung midden is kind of like a toilet or an outhouse. It\u2019s where the hippos go repeatedly to poop. But, as Stears told us, it also serves another purpose. While humans can\u2019t tell their poop from someone else\u2019s, other animals can sniff out individuals this way, and use dung or urine\u2014pee\u2014to mark their territories.
\n\nHippos aren\u2019t the only animals to use dung middens this way, by the way. Rhinoceroses do this too! Other animals, like dogs, cats, rabbits and monkeys also sniff feces and urine as a way to learn about their fellow species, but they don\u2019t always leave their \u201cmessages\u201d in the same place.
