Crawling Water Beetle
A tiny, oval water beetle with a yellowish body covered in rows of dark punctures. Unlike diving beetles, it crawls slowly among aquatic vegetation rather than swimming actively.

It stores air beneath enlarged hind coxal plates, which act as a built-in oxygen reservoir while submerged.
Nebrioporus Water Beetle
A small diving beetle endemic to Japan found in clean mountain streams. Part of a genus that prefers running water over still pools. An indicator species for unpolluted waterways.
