OPM Termite Practice Exam

What characteristic differentiates Soldiers in the termite caste system?

1. Large wings

2. Specialized mandibles

3. Color variation

4. Smaller body size

The correct answer is: Specialized mandibles

In the termite caste system, Soldiers are primarily differentiated by their specialized mandibles. These mandibles are significantly larger and more robust compared to those of other castes, such as workers or reproductives. This adaptation is essential for their role in the colony, as Soldiers are responsible for protecting the nest from predators and intruders. Their powerful mandibles allow them to defend the colony effectively, which is crucial for its survival. The other characteristics mentioned do not apply to Soldiers in the same way. For instance, Soldiers do not have wings; in fact, they are wingless, unlike the reproductive termites. Additionally, while color variation can exist among different castes, it is not a defining characteristic that sets Soldiers apart. Lastly, Soldiers generally have a larger body size compared to the worker caste, not a smaller one. Therefore, the specialized mandibles are the key distinguishing feature that defines the Soldier caste within a termite colony.
