They Love Small Talk
Humans love small talk, and otters love small talk. It’s like a match made in heaven! A study in 2014 revealed that river-dweller pups “have 11 of their calls that they intersperse with “infant babbling.” Among the most notable calls: a “hum gradation” used to tell otters to change directions and a “Hah!” shout when a threat is nearby.” This is the otter pup’s small talk. All they need to do is make a few sounds and their adults will know exactly what’s going on (Mental Floss).
