This weird-looking primate’s extra-long fingers give it an extra-gross talent
Humans aren’t the only animals to pick their nose and eat the contents, a new study has shown.
Researchers have for the first time documented the behavior ∈a primate known as the aye-aye, a most unusual-looking species of lemur. The Journal of Zoology published the findings on Wednesday.
Anne-Claire Fabre, a curator at the Natural History Museum of Bern, ∈Switzerland, and associate professor at the University of Bern, observed an aye-aye picking its nose while she was filming the animals at the Duke Lemur Center, a sanctuary and research facility ∈Durham, North Carolina.
Using a low-light camera, Fabre captured the female aye-aye, known as Kali, indulging ∈ this questionable pastime.
“It was impossible not to notice this ayeaye picking its nose,” Fabre, the study’s lead author, said ∈a statement.
“This was not just a one-off behaviour but something that it was fully engaged ∈, inserting its extremely long finger a surprisingly long way down its nose and then sampling whatever it dug up by licking its finger clean!”
Including aye-ayes and humans, 12 species of primate have been observed snacking on snot.
Unlike humans’ relatively short digits, the aye-aye’s long and skinny \middle finger is perfectly shaped for deep digging. A reconstruction of the animal’s nasal passage based on a CT scan suggests its curved finger can reach all the way back into its throat to root around for mucus.
