How many segments do ants' antennae typically have?

Ants' antennae are typically composed of 9 or 11 segments, which play a crucial role in their sensory perception. These segments are designed to enhance the ant's ability to detect chemical signals, pheromones, and environmental cues. The structure of the antennae varies among ant species, but the most common range falls within 9 to 11 segments.

Having this specific number of segments allows ants to engage with their environment more effectively, as these antennae are essential for communication and navigation. Different lengths and segments help ants fine-tune their sensory capabilities, which is vital for their colony organization, foraging behavior, and social interactions.

The other options do not accurately reflect the common segmentation of ant antennae, as they either suggest fewer or greater segments than what is typically found in ants.
