   Why are night monkeys called Aotus?

   • Their genus name (Aotus) means “earless,” and was chosen because their ears can be difficult to see. As mentioned, Colombian night monkeys live in small family groups, which essentially move together as one. They’re never more than 32 feet (approximately 10 m) from one another.

   Why are monkeys called Aotus?

   • It is likely that they select branches surrounded by many lianas so they are hidden from predators. This monkeys’ scientific name is composed of two words: aotus, which means earless, and Azara, in reference to a Spanish naturalist named Felix Manuel de Azara (1742–1821). Several animals are named after him.
