sloth
Juvenile three-toed sloth (Bradypus) climbing a tree branch.
The three-toed sloth (family Bradypodidae) is commonly referred to as the ai in Latin America because of the distinct, high-pitched cry or screech it produces when it is agitated or disturbed.12
The name is derived from the Tupi language, and while the animal is typically silent and docile, this vocalization serves as a notable characteristic that led to its regional name.12
