沙泡蟹的觅食模式在热带海滩上形成小沙球堆。

ose-up captures the fascinating feeding behavior of a sand bubbler crab, common along Indo-Pacific tropical beaches. During low tide, these tiny crabs sift sand for microscopic food particles, rolling the leftover grains into tiny pellets and discarding them on the surface. Their methodical, spiraling work creates distinctive patterns and piles of sand balls, preventing them from reprocessing the same sand twice and leaving intricate natural designs across the beach.
