When preparing for a date, a human might use a small spritz of cologne or perfume.

And male ring-tailed lemurs also splash on some cologne to impress the females.

The only difference is they secrete their own sense from glands near their wrists. And during the breeding season, the males rub the secretions from their wrists onto their tails,

and then wave the tails near females.

Researchers actually call this behavior stink flirting.

Biologists already knew that lemurs have scent glands and that they use them to communicate

their social rank or to identify their territories. Scientists also knew that sometimes males

use their scent glands as part of a dominance display against potential rivals. But nobody had really

looked to see whether the females were relying on the

male sense as part of their mate selection process. Nobody until Kazushige Tohara, a biological

chemist at the University of Tokyo. Working at a wildlife laboratory, he and his team collected

the secretions from male ringtail lemurs

risk lands twice a month for several years. In an email, he described the male scent as fruity and

floral. The researchers identified three chemical compounds in the secretions that were in higher

concentrations during the breeding season, which suggested
