Ants Clean Their Antennae With Built-In Combs
Ants need to be fastidious about cleaning their antennae. If they're too gunked up, the sensitive organs won't be able to lead them to food or communicate with other ants. In 2015, scientists at Cambridge University got close enough to learn how Camponotus rufifemur ants kept their antennae spotless: they used a small, lobster-claw-like structure on their front legs that's lined with three different types of hairs. They called these hairs "bristles," "comb," and "brush." An antennae passes through them in that order, leaving foreign particles behind.
