“Crab moving forward”

I went to the mouth of the river that runs near the industrial road. The sea had receded and turned into mudflat. Walked on mudflats with stones and puddles. There were many round-bodied crabs. On closer inspection, those crabs were walking forward. They didn’t notice me and hide under stones like other crabs, but moved around looking for food. [2025 JUNE]
