Korean Water Scorpion
A flat, leaf-shaped aquatic predator found in Japan and Korea. Despite its name, it is not a true scorpion but a true bug with raptorial forelegs. Breathes through a siphon-like tail appendage.
Did You Know?
The long breathing siphon at the rear works like a snorkel, allowing the water scorpion to breathe while remaining submerged and hidden among leaf litter.
Chinese Rhagophthalmid Glowworm
A bioluminescent beetle from southern China with larviform females that emit a steady greenish glow from ventral light organs. Males have well-developed wings but vestigial mouthparts.
Did You Know?
This species has been studied for its unique luciferase, which differs significantly from that of the related firefly family Lampyridae.
