Detroit Zoo Presents: Jagger the sloth bear's snout. Her long, hairless nose and wide nostrils are great for sniffing out insects. After finding the goods, sloth bears can seal up their nostrils to prevent their future food from crawling in. 🐜 They also lack their two-front teeth, allowing them to suck up small insects easily. #DetroitZoo #SlothBear #AnimalAdaptations 📷 Roy Lewis.
