There are over 700 species of gobies living in mostly tropical waters of the Indo-Pacific, Mediteranean, and Carribean. They are one of the most successful fish families. Here in the Pacific Northwest, we only host the handful of species that can tolerate our colder waters.
Gobies ususally live in shallow to moderate depths. They like silty bays and tidal flats, but some are found among rocky outcroppings. Some species will contruct burrows in the sand, and others will inhabit existing burrows built by crabs and shrimp (along with the original inhabitants). Gobies are small fish; few get bigger than six inches in length.
