Shuttles Hoppfish is a rare ornamental fish, belonging to a small tropical fish, which is distributed in the South China Sea and the East China Sea of Malaysia, Korea, Japan and China; It inhabits in the saltwater and fresh water area of the estuary, near the beach or in the low tide area with muddy bottom, and has strong water quality tolerance to the harsh environment.
Shuttles Hoppfish like to live in the coastal shoal, like to live in the low-lying area of soft mud bottom or the estuary shoal of semi salt water. With the help of ventral fins, you can crawl on mud to play, chase, jump and forage, so it’s called skipper. Taking benthic diatom as the main food, it is a kind of precious fish species. From the perspective of food, it takes the pollution-free sea beach as the top product.
The Shuttles Hoppfish is widely salinated and likes to live in caves. The caves are generally Y-shaped, which are composed of channels, positive orifices and back orifices. The positive orifice is used for inlet and outlet, and the rear orifice is used for air exchange. Crawling or jumping on water surface, beach and rock by means of pectoral fins and tail stalks; crawling on mud to find benthic diatoms, cyanobacteria, and a small amount of copepods and organic matter.
How does the Shuttles Hoppfish jump? Originally, when leaving the water for a long journey, the elastica had a saliva in its mouth to prolong its stay on the land. Because the saliva in the mouth can help it breathe, just like the oxygen tank on the back of a diver is full of air, while the “air tank” of a trawler is a mouth full of water. The ventral fins of the tilapia have evolved suction cups that help it stay firmly in its place. The strong abdominal fins support the body, while the well developed pectoral fin muscles pull the body forward so that the fish can move on land.
Some studies have also found that elastica can transport air, and the reason is not difficult to explain. The skin of large elastica can directly absorb oxygen in the air; one liter of water contains about 10 cubic centimeters of oxygen, while one liter of air contains as much as 210 cubic centimeters of oxygen; air will gather in a closed container; air specific gravity ratio The water is light, always running to the water. Therefore, some people think that the fish can transport air.
