What is the primary theorized function of the shorter pair of antennae on the woodlouse head?
Answer
Chemoreceptors for sensing smells
Woodlice possess two pairs of antennae on their head structure, each specialized for different sensory inputs necessary for navigating their dark, damp habitats. The shorter pair is primarily theorized to function as chemoreceptors, meaning their role is focused on detecting chemical signals in the environment, essentially enabling the woodlouse to sense smells. In contrast, the second, longer pair of antennae is equipped with fine, hair-like structures called setae, which are responsible for tactile sensation, helping the creature perceive physical contact and environmental cues through touch.
