Fish physiology. When threatened, the toxic pufferfish fills its extremely elastic stomach with water. [1] Fish physiology is the scientific study of how the component parts of fish function together in the living fish. [2] It can be contrasted with fish anatomy, which is the study of the form or morphology of fishes.
Tilapia, often farmed, is a popular and common supermarket fish in the United States. [citation needed] In India, Nile tilapia is the most dominant fish in some of the South Indian reservoirs and available throughout the year. O. niloticus grows faster and reaches bigger sizes in a given time. The littoral areas of Kelavarappalli Reservoir are ...
The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ that contributes to the ability of many bony fish (but not cartilaginous fish) to control their buoyancy, and thus to stay at their current water depth without having to expend energy in swimming.
Urechis unicinctus, known as the fat innkeeper worm or penis fish, is a species of marine spoon worm in East Asia. It is found in Bohai Gulf of China and off the Korean and Hokkaido coasts. [4] It is not to be confused with a closely related species, Urechis caupo , which occurs on the western coast of North America and shares common names. [5]
Physostomes are fishes that have a pneumatic duct connecting the gas bladder to the alimentary canal. This allows the gas bladder to be filled or emptied via the mouth. This not only allows the fish to fill their bladder by gulping air, but also to rapidly ascend in the water without the bladder expanding to bursting point.
Wilfley table. The Wilfley Table is commonly used for the concentration of heavy minerals from the laboratory up to the industrial scale. It has a traditional shaking (oscillating) table design with a riffled deck. [1] It is one of several brands of wet tables used for the separation and concentration of heavy ore minerals which include the ...
The fish are often "conditioned" (starved) before they are transported to reduce their metabolism and increase packing density, and the water can be cooled to further reduce metabolism. Live crustaceans can be packed in wet sawdust to keep the air humid. By air: Over five percent of the global fish production is transported by air.
Tropical wet forests are characterized by the complex, physical structure of the ecosystem. There are many layers of plant communities, though they are rarely visible from the ground. Shrubs and creepers fill the forest floor with saplings dispersed throughout. Large trees hold their full crowns in the canopy, prohibiting sunlight from plants ...
Lake Makgadikgadi ( Setswana: Letsha la Makgadikgadi, [lɪt͜sʰa la makχʰadiˈkχʰaːdi]) was a paleolake that existed in what is now the Kalahari Desert in Botswana from 2,000,000 years BP to 10,000 years BP. It may have once covered an area of from 80,000 to 275,000 km 2 (30,888 to 106,178 sq mi) and was 30 metres (98 ft) deep. [1]
Taiyaki (鯛焼き, lit.'baked sea bream ') is a Japanese fish -shaped cake, commonly sold as street food. It imitates the shape of tai (鯛, red sea bream), which it is named after. [1] The most common filling is red bean paste that is made from sweetened adzuki beans.
