Abstract: Abstract: The nervous system of the nematode Caenorhabditis elegans is well functional despite its smallness in size and simplicity in structure. The ability of perception of environmental cues makes C. elegans explore its environment and move to favorable surroundings. The sensory functions and mechanisms in C. elegans are always being the research focuses of neuroscientists. In this review， the recent progress of sensory study in C. elegans is summarized， including mechanosensation， chemosensation， thermosensation， light sensation， nociception， oxygen and dioxide sensation， and hygrosensation. This may provide insights on the sensory study into both C. elegans and higher animals.
