Why don't anteaters get stung on their tongues?

Anteaters have specialized tongues that are long, slender, and covered in a sticky saliva, allowing them to efficiently capture ants and termites. Their tongues are also protected by a layer of keratin, which helps to prevent injury from bites or stings. Additionally, anteaters have a low body temperature, making them less attractive to the insects they consume, and they have a unique feeding strategy that minimizes exposure to the insects' defenses. As a result, they can feed on their prey without getting stung.
