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 (Gobius niger) is a species of ray-finned fish found in the Eastern Atlantic and Mediterranean Sea and Black Sea. It inhabits estuaries, lagoons, and inshore water over seagrass and algae. It feeds on a variety of invertebrates and sometimes small fish. This species can also be found in the aquarium trade. [2]

A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
The knight goby benefits from a fluctuation in temperature over a 24-hour period, with a lower temperature at night. They will tolerate temperatures between 20 and 26 °C (68 and 79 °F). It is not essential, but the fish will do better with 1–2 level teaspoons of salt per 11 litres (2.5 gallons). [4]
