What insect has fifteen body segments and a pair of legs for each segment?

The Texas Giant Centipede is characterized by having a segmented body with fifteen body segments, and it possesses a pair of legs for each segment. This is a defining trait of centipedes in general, as they have a unique body structure that allows them to move quickly and efficiently through soil and leaf litter. The structure of centipedes allows for heightened mobility, making them effective predators of other small invertebrates.

The presence of a pair of legs per segment is a key aspect that differentiates centipedes from other similar creatures. While millipedes also have many segments and legs, they typically have two pairs of legs per body segment. Other options, like the Common House Centipede and Scutigera, also belong to the centipede family but may not necessarily conform to the 15 segments and their leg arrangement as described for the Texas Giant Centipede. Therefore, the Texas Giant Centipede stands out as the correct answer based on its specific anatomical characteristics.
