Description
The riverine stargazer is a small bottom fish of the sand stargazer family (Dactyloscopidae) from the eastern Pacific, along the coast of Central America. The species reaches only a few centimetres and has an elongate body with upward-directed eyes and mouth. Unlike most sand stargazers it tolerates brackish water and occurs in estuaries and the lower reaches of rivers. It largely buries itself in the sand, with only the eyes visible, and seizes passing small bottom invertebrates. Owing to its hidden habits the species is little noticed.
