Round gobies are invading inland water from the Great Lakes, where they negatively impact ecosystems by eating the eggs of native fish. [17] The GRCA reports that round goby is present as far north in the watershed as Belwood Lake, [18] and the species has been detected in most of the systems surrounding Mill Creek. [19]
Neogobius pallasi (Berg, 1916) (Caspian sand goby) Of these, N. bathybius, N. caspius and N. pallasi are endemic to the Caspian basin.

The western tubenose goby have tubular nostrils and its nostril tube extends to the upper lip. The tubular nostril is 2–4 centimeters long. The round goby lacks these nostril ...
The northern tidewater goby prefers salinities of less than 10 ppt. Juveniles have been found as far upstream as 12 km, e.g. in Ten Mile River, Mendocino County, and San Antonio Creek and the Santa Ynez River, Santa Barbara County, sometimes in sections of stream impounded by California Golden beavers (Castor canadensis subauratus) which ...
