Bare-footed and bent double, children pluck worms (cacing laut) from the wet sand at the shoreline. They carry two small buckets in one hand: one for the collected worms, and one with water which they sprinkle onto the sand after the waves recede.
The worms can be sold as fishing bait for Rp 1,000 ($0.10) per kilo.
