Global InformationShimofuri goby information
The Tridentiger bifasciatus is found in fresh and brackish waters. However, it is most abundant in low-salinity environments. The fish has typical features consistent with the family Gobiidae and grows to a maximum of 12 centimeters. These characteristics include two pelvic fins united from a conical sucking disk, a spiny anterior and a soft posterior dorsal fin, and eyes near the top of the head.[1] These fins typically have 6-7 spines and 11-14 rays with orange tints on the edges. The Tridentiger bifasciatus has a flat wide head and is highly variable in color, but generally light or dark brown with midlateral spots and miniscule white spots on the head.[1]
The native range of the Tridentiger bifasciatus is fresh and brackish water habitats in Asia. This includes Japan, Korea, China, Taiwan, and the former Soviet Union.[2]
The Shimofuri goby is widely distributed in the San Francisco estuary. By 1990, the species traveled down to the Pyramid Lake in Los Angeles County.[2] By 2016, the Shimofuri goby has been found in seven southern California reservoirs.[3] There are 9 total locations with observations that include Los Angeles, Lower Sacramento, San Diego, San Francisco Bay, San Joaquin Delta, San Pablo Bay, Santa Clara, Santa Margarita, and Suisun Bay.[1] The Shimofuri goby is still distributed in its native Asian estuaries which include China, South Korea, Japan, and Russia.[3]
