Microgobius
Microgobius is a genus of gobies in the family Gobiidae. The genus has only three known species: Microgobius carri, Microgobius gulosus, and Microgobius thalassinus. These small, bottom-dwelling fish are found in marine environments along the western Atlantic coast of North America, from the Carolinas to Florida. The genus name Microgobius is derived from the Greek words “mikros” (small) and “gobios” (goby), reflecting their diminutive size.
Common Names
The common names for Microgobius species vary, but some frequently used terms include:
- Carri's Goby (Microgobius carri)
- Greedy Goby (Microgobius gulosus)
- Shrimp Goby (Microgobius thalassinus)
Characteristics
Microgobius species share several key characteristics:
- Small size: They are typically less than 2 inches (5 cm) in length.
- Elongated body: Their bodies are slender and elongated, with a slightly compressed shape.
- Fused pelvic fins: Like most gobies, they have a pair of pelvic fins that are fused together to form a suction disk, which allows them to adhere to surfaces.
- Coloration: The coloration of Microgobius species can vary, but they typically have a mottled or speckled pattern, often with brown, gray, or orange hues.
Environments
Microgobius gobies are found in a variety of marine habitats, including:
- Seagrass beds: They are often found associated with seagrass meadows, using the vegetation for shelter and food.
- Mangrove swamps: Some species, like the Shrimp Goby (Microgobius thalassinus), inhabit mangrove swamps, particularly in the roots and crevices.
- Rocky reefs: They can also be found among rocky reefs, utilizing the cracks and crevices for refuge.
- Shallow waters: Microgobius species generally prefer shallow, inshore waters, often in areas with moderate water flow.
