What is a defining characteristic of centipedes?

A defining characteristic of centipedes is that they possess one pair of legs per body segment. This unique feature allows them to be distinguished from other similar arthropods. Centipedes are elongated, multi-segmented creatures, and each segment typically contributes to their mobility through the presence of a single pair of legs.

This adaptation aids in their agility and speed, making them effective predators in their environments. Their body structure facilitates a smooth, undulating movement, which can be crucial for hunting smaller prey. The presence of one pair of legs per segment is a consistent trait across various centipede species, reinforcing their classification within the class Chilopoda.

In contrast, options involving multiple pairs of legs per segment or having wings do not apply to centipedes and instead may describe different classes of arthropods, such as insects, which can have two pairs of wings or two pairs of legs per body segment.
