Justification
The Taboga Goby (Microgobius tabogensis) has been assessed as Least Concern. This species is common and widespread in the Eastern Pacific region. Although this species may be locally threatened by habitat loss from coastal development and the removal of mangroves within its range, there is no current indication of widespread population decline.
