This ancient species featured paddle-like limbs designed for swimming and additional legs on its abdomen, indicating a semi-aquatic lifestyle in shallow coastal regions. This find is crucial in understanding the slow, gradual adaptations insects underwent over millions of years in their evolutionary history.
