What is a distinctive feature of termite bodies?

A distinctive feature of termite bodies is characterized by a broadly joined abdomen and straight antennae. Termites possess an elongated and cylindrical body shape, which contributes to their unique appearance. The broad connection between the thorax and abdomen differentiates them from other insect families and aids in their identification.

Termites have straight (not curved) antennae, which is another key identifying trait. These straight antennae are segmented and help with communication and navigation within their environment. This specific anatomy is part of what classifies termites within the order Isoptera.

The other descriptions provided do not accurately reflect the physical characteristics common to termites. For instance, a flat abdomen or curved antennae does not align with termite morphology, as termites do not exhibit those features. Similarly, the narrow waist and long antennae mentioned in other options better describe ants rather than termites. A segmented body and short legs are general features shared among many insect types but do not specifically highlight the distinctive aspects of termite anatomy. Therefore, the answer effectively captures the critical identifying features of termites.
