Etymology: Polyspondylogobius: Greek, poly = a lot of + Greek, spondylos = vertebra + latin, gobius = gudgeon (Ref. 45335); sinensis: From the old name for China. Polyspondylogobius comes from the Greek term "poly" for many, and "spondylos" for vertebra, which refer to the uniquely numerous vertebrae of the species.
