Sperm proteins presumably play critical roles in reproduction, but in many non‐model animals their identities are unknown. A total of 147 sperm proteins from the echiuran worm Urechis unicinctus, the first sperm proteome in the phylum Annelida, are reported. The echiuran sperm proteome can be classified into diverse functional groups: energy metabolism (31%), protein synthesis and degradation (18%), spermatogenesis and sperm motility (12%), signal pathway (11%), ion channel and transport proteins (6%), cytoskeleton (4%), immunity and stress responses (3%), and fertilization (1%). These results will facilitate studies of mechanisms of fertilization in echiurans, as well as comparative studies of reproduction and evolution across lophotrochozoans. Data are available via ProteomeXchange with identifier PXD009176.
