Some clues about why male Guinea baboons fondle each other’s genitals

Plenty of animals have ritual greetings. But most are not like this.

Whales are stressed out by climate change, and it shows in their earwax

Earwax tracks the rise and fall of cortisol alongside whaling, war, and warming

Chimps have different cultural norms about friendliness, too

Generalizing from one group of chimps to the whole species is a sticky business.

This dog-faced bat is a very good boy… with wings

Bats have a nasty reputation for being creepy, dangerous, and sometimes turning into blood-sucking vampires, but nothing could be farther from the truth. Bats are incredibly special animals that are in desperate need of a PR makeover, and I think we’ve found the mascots that might be able to turn things around.

The adorable little fella you see above belongs to a group called “dog-faced bats,” and there’s more of them now than ever before. In research that came out earlier this year, a pair of new dog-faced bat species was officially added to the bat roster, and they are very good bats.

The bats, which Smithsonian perfectly describe as “sky puppies,” were identified by specimens gathered a number of years ago. The process of differentiating closely related species can take a while, but the verdict was finally reached and the two new species, the Freeman’s dog-faced bat (seen above) and the Waorani dog-faced bat. The animals were found in Panama and Ecuador, respectively.

“After characterizing the body shapes of 242 dog-faced bats from museum collections across the Americas and Europe, comparing their DNA, and adding in field observations including sound recordings, we consider there to be eight species in this group, two of them new to science,” Ligiane Moras, who led the research, said in a statement.

There’s lots of interesting details in the paper, which was published in Mammalian Biology, so feel free to dive into that if you’re looking for the nitty gritty, but I’d rather talk about how cute these friggin’ bats are. I mean look at this guy, which is one of the newly-classified Waorani dog-faced bats:

Look at him! All he wants to do is hang out, eat some bugs, and smile at passersby. Frankly, these bats look like the only thing they need from humans is a nice little belly rub. I would be happy to volunteer.

Cooperation is cultural

How you manage cooperation depends on how you perceive its lack.
