THE apex of animal social organization is eusociality, which has three characteristics: overlapping generations, reproductive division of labour, and cooperative care of young1,2. So far, eusociality has been recognized only among social insects and the African mole-rats3–5. Here I report the first case of eusociality in a marine animal. The sponge-dwelling shrimp Synalpheus regalis lives in colonies that may have >300 individuals, but that contain only one reproductive female. Direct… Expand
