claws
螯 centers on the pincer-like claws of arthropods such as crabs or scorpions. The meaning is specific to these grasping appendages.
螯 combines 敖 (a phonetic component suggesting a proud or prominent shape) with 虫 (insect or small creature), indicating the prominent claws of certain creatures. The exact historical development is uncertain.
The top part 敖 looks like a proud, raised structure, and the bottom 虫 is a creature. Imagine a crab proudly raising its claws: 螯 means claws.
For ゴウ, picture a crab going 'gou gou' as it snaps its claws: the sound 'gou' cues ゴウ while the claws snap.
