Valenciennea puellaris, the Orange-spotted sleeper-goby, Orange-dashed goby, or Maiden goby, Diamond Watchman goby, is a species of goby native to the Indian Ocean and the western Pacific Ocean. It inhabits lagoons and outer reefs where it occurs on sandy substrates with larger pieces of rubble to burrow under.
The Gobi Desert is the fastest expanding desert on Earth, as it transforms over 3,600 square kilometres (1,400 square miles) of grassland into wasteland annually. [58] Although the Gobi Desert itself is still a distance away from Beijing , reports from field studies state there are large sand dunes forming only 70 km (43.5 mi) outside the city.
The black goby is deeper-bodied than the common goby, sand goby and two-spotted goby with a more rounded snout and generally a larger size. It has two dorsal fins that are almost continuous, the anterior one having six spines, which may project from the fin membrane, and the posterior and shorter one having soft rays.

The males display brilliant blue and red colours during the breeding season, colours which change with the mood of the fish. The females attach their eggs to rocks where they are fertilised by the males, and the hatchlings are immediately washed downstream into the sea, where they develop, later to return to the freshwater pools upstream, where ...
Male northern tidewater gobies burrow into sand and mud in the spring, cementing together grains of sand with a mucous, and shutting the burrow off from the waters above with a mucous and sand plug. Females will become aggressive during the spring and fight over a potential mate, slapping each other with their tails and biting when posturing is ...
