A newly recorded species Caprella mutica Schurin, 1935 belonging to the family Caprellidae Leach, 1814 was collected from the East Sea, Korea. Caprella mutica is native to the north-east Asia but is a well-known cosmopolitan and invasive species in many areas. This species is morphologically highly similar to C. acanthogaster Mayer, 1890. However, it is distinguished from a combination of the characteristics of the head, pereonites 1-2, and gnathopod 2. In this study, the Korean C. mutica is fully illustrated based on the mature specimens and compared to C. acanthogaster.
