There are five critically endangered gobies, 18 listed as vulnerable, and 12 listed as low risk. Agricultural practices and the introduction of non-native species are some important causes for their decline. This is not surprising considering the diversity of this family and the fact that many are confined to a single lake or river system, or one or few islands. Some may go extinct before humans become aware of their existence.
