Morphological characteristics of alligator acutus
The body length is 40-50CM, and the longest is reported to be 6 meters, which is a long cylinder. The mouth protrudes forward, and the upper and lower jaws have bone plates and teeth, which are similar to the mouth of an crocodile. The body is blue-gray, with dark black patterns on the body surface. The skin is covered with hard scales, thick and rough.
Life habits of alligators
The inlet water temperature is 20-26℃, and the water quality requirements are not strict. Bait includes small live fish, fish, water worms and so on. These are very easy to raise. It is difficult to breed in an aquarium. Sparrow eel (meaning spear in British Saxon) is a freshwater fish, which lives in tropical rivers and lakes in South America, Central America, Mexico and the West Indies.
Crocodiles? This is a freshwater fish. The general water temperature is 18-26℃, which does not require high water quality, but it is difficult to cultivate in an aquarium.
The main species of alligators
Monopterus albus, with a body length of 1.5m, elongated into a cylinder, dark brown body, light abdomen, hard scales on the back, and various fish patterns, ranging from few to dense parts with fine patterns. Young fish have dark longitudinal stripes on their backs and sides, which are distributed in the Great Lakes and Mississippi River basins of North America. They inhabit freshwater rivers, lakes or brackish lagoons and estuaries and are carnivorous.
Florida finch eel, with a body length of 1.32 m, is similar to spotted finch eel, but has a short bill, and there is no bone plate in the ventral part of adult fish head, which is distributed in fresh water and brackish water basins in Florida, USA. The difference is the former. The back of the body is dark brown, the abdominal pattern is changeable, and sometimes there are stripes on the side. It lives in freshwater rivers, lakes or brackish water with sandy bottom. It is a carnivore and feeds on crustaceans, fish and insects.
The main harm of crocodiles
Sparrow eel is a fierce carnivorous fish with a long mouth and sharp teeth. This fish will attack all the fish it meets. When it preys, it will pretend to be dead until the prey gets close to it, and then it will turn around the bitten fish once or twice before eating. Local fishermen regard it as an ominous thing because there are few other fish in the place where it lives. Local fishermen are generally unwilling to eat this kind of fish and are not suitable for eating. Eels have diamond-shaped scales all over their bodies, which look as hard as the armor worn by warriors. It is actually composed of inorganic salts. Many extinct ancient fish also have this scale. Like other ancient fish, the finch eel has a swim bladder connected to the esophagus, which can be used for breathing. The eggs of Monopterus albus are extremely toxic, and if eaten by humans or other warm-blooded animals carelessly, it will lead to death. From North America. Its long and powerful mouth makes it a fierce carnivorous fish in fresh water. It absorbs oxygen from the air with a human-like nose. Sparrow eel is closely related to bowfin fish and has existed since ancient times. Fossils 65438+200 million years ago were found in Europe. The body is covered with diamond-shaped hard scales, which are very hard. Most kinds of mouths are like crocodiles.
Because of its fierce nature and strong viability, if it is allowed to breed locally, it will cause great harm to local fisheries. It is very dangerous to appear in natural waters, mainly meat, and it is very likely to cause devastating damage to local fish.
In Guangdong, there used to be a farmer's fish pond? Fuck? Two finches were brought in, and the fish in the whole pond were eaten up in one month, which shows the degree of harm. In addition, because the eggs of the eel are highly toxic, once someone eats them by mistake, they may be fatal.
If citizens find eels or other exotic species, they should report to the fishery administration department in time, and they are not allowed to release exotic species into natural waters at will, so as to avoid biological invasion and irreparable losses to local fish resources and species.
