The Rhinogobius giurinus is a type of small fish called a goby. It lives in eastern Asia. This fish can be found in many different kinds of water. It lives in salty ocean water, slightly salty water (called brackish water), and fresh water in rivers and estuaries.
This interesting fish can grow up to about 8 centimeters (about 3 inches) long. People in the areas where it lives often catch and eat it as a food fish.
Where the Goby Lives
The Rhinogobius giurinus is naturally found in many parts of Asia. Its home includes major rivers like the Yellow River, Yangtze River, and Pearl River in China. You can also find it in Taiwan, Hong Kong, and the Korean Peninsula.
In Japan, it lives from the Tone River all the way to Iriomote. It is also found in the Bonin Islands, Ryukyu Islands, and northern Vietnam. This shows it has a very wide natural range!
Sometimes, this fish is also found in new places. For example, it has been introduced to Singapore and parts of the Tibetan Plateau.
Goby Habitats
This goby fish is very adaptable. It can live in many different places. Its homes include rivers, large reservoirs, ponds, and estuaries. Estuaries are places where rivers meet the sea.
Even though it is a migratory fish (meaning it sometimes moves between different water types), it can still live and have babies in a completely closed drainage system. This means it can survive even if it can't move freely to other bodies of water.
What the Goby Eats
The Rhinogobius giurinus has a varied diet. It eats many different things it finds in the water. Its meals include small aquatic insects and other tiny invertebrates.
It also eats very small fish. The goby feeds on tiny living things that float in the water, like zooplankton (tiny animals) and phytoplankton (tiny plants). It even eats small pieces of dead plants that sink to the bottom.
