Solitary river otters in Brazil use a rich repertoire of vocalizations during play and conflict, according to a study publishing May 26 in the open-access journal PLOS ONE, by Sabrina Bettoni, Tecumseh Fitch, and colleagues at the University of Vienna.

The naked mole rat may not be the most attractive rodent on the block, but it’s still a social butterfly. These hairless, mostly blind and deaf animals live in colonies of up to 300 individuals, which communicate with high-pitched squeaks. Now, researchers have discovered that, like humans and many birds, mole rat communities have their own dialect, which is kept alive by their queen.
“The study is exciting because it provides the first evidence for vocal learning in a rodent,” says evolutionary biologist Tecumseh Fitch at the University of Vienna, who was not part of the work. More research, he says, may help scientists better understand how complex vocalizations evolved in social animals, including humans.
