The world's smallest fish? The goby is known as the smallest fish in the world, and is generally distributed in the Philippines. It is about 0.6 cm long and is the smallest fish in the world. Baked tiger fish live in some rivers and lakes in the Philippines, and there are some in the ocean around the Philippines. Perhaps because it is too small, it looks like a shrimp instead of a fish, so people call it a goby. The goby is 2000 times different from the whale shark, the largest fish on earth. When the baked tiger fish eats, it swallows the sand and mud into its stomach, and then filters out the food from the gill cover. The range of activities of gobies is not large. Many gobies live with invertebrates such as corals, sponges and sea whips. Although the goby is small, it has strong fecundity, so the number of individuals is very large, and local residents in the Philippines often catch them as food. Local women put goby into a special glass bead fish tank and make earrings to wear, which is very interesting. Besides being small, goby is also the shortest life-span vertebrate in the world, generally living for 2-3 years, up to 4 years. A fish on Australia's Great Barrier Reef can live up to 59 days. ? The goby, the smallest fish in the world, was replaced by a new fish called chubby baby fish in 2004. ? The scientific name of "fat baby fish" Schindleria brevipinguis, also known as Stout micro-fish, is slender and looks like a bug. They have no fins, no teeth and no scales. The body has no pigmentation except the eyes and is transparent. Female fish lay eggs when they are 2 ~ 4 weeks old. The life span of "fat baby fish" is about 2 months, so it is called "the smallest fish in the world". On July 8, 2004, in the latest issue of Research Magazine published by Australian Museum, Australian scientists officially announced that they had confirmed the smallest and lightest fish in the world. This fish is only about 7 mm long and weighs 1 mg. Only one million fish can make up 1 kg, so it is a well-deserved "junior" among vertebrates. Scientists have registered this fish as a new species and declared it as the smallest vertebrate in the Guinness Book of Records. The average male body length of this fish is only 7 mm, and the average female body length is about 8.4 mm. It is estimated that even the smallest hook can't be swallowed by them. Besides goby and chubby baby fish, there are two kinds of fish that are also very good, and the country has become the smallest fish in the world? True catfish-common name Liugen fish is distributed in the upper reaches of Heilongjiang, Nenjiang and Suifenhe rivers, and also found in Yalu River, Irtysh River and Tumen River in Xinjiang. ? The smallest fish in Sumatra in 2006 1 month, the fish found by scientists in the forest swamp of Sumatra, Indonesia won the title of the world's smallest fish, with a body length of only 7.9 mm.
