The finch eel is the eel family (Lepisosteidae) finch eel genus (Lepisosteus) of large fish collectively, produced in North or Central America. It is closely related to the bowfin fish and belongs to the Holostei. It mainly inhabits freshwater, but some species can descend into semi-saline or even brackish water. It often floats like a log in slow-moving water to bask in the sun and breathe atmospheric air. It is a large, aggressive, carnivorous fish with sharp teeth, a backward dorsal fin, and a rounded caudal fin, the longest of which has been reported to be up to 6 meters. The flesh of the sparrow eel is edible, but the eggs are poisonous.

Edit Introduction
The finch eel The finch eel, Duckbill Crocodile, belongs to the finch eel family of the order Finch Eel. Originally from the Great Lakes region of North America, it belongs to the finch eel family. The body length is 40-50cm, long and cylindrical. The mouth protrudes forward, upper and lower jaws have bony plates with teeth, resembling the mouth of a crocodile. The body is greenish gray with dark black patterns on the body surface. Sparrow eel
Skin covered with hard scales, hard scaly skin, rough skin. The sparrow eel [which means spear in Anglo-Saxon] is a freshwater fish that lives in tropical rivers, lakes in the southern United States, Central America, Mexico, and the West Indies. The sparrow eel is a fierce predator fish with a long mouth and sharp teeth. This fish will attack all the fish it meets, feeding, it will be motionless play dead, until the prey close to it when the fatal blow, and then around the bite of the fish around one to two circles before eating it. Local fishermen regard it as an ominous thing, because there are few other fish in the place where it lives. Local fishermen are generally reluctant to eat this fish, and it is also not very fit for consumption. The sparrow eel is covered with a layer of diamond-shaped fish scales, which looks unusually tough like the armor worn by a samurai, but it is actually composed of inorganic salts. Many extinct ancient fish also have these scales. Like other ancient fish, the sparrow eel had a swim bladder attached to its esophagus, which it used to breathe. Sparrow eel eggs are extremely poisonous and inadvertent consumption by humans or other warm-blooded animals will result in death. It comes from North America. The long, powerful mouth makes it a ferocious, carnivorous fish in freshwater. It uses a unique air sac as a respirator to suck oxygen from the air. The sparrow eel is closely related to the bowfin, a fish that has survived from ancient times. Now found only in and around North America, but in ancient times the fin eel
Distributed in freshwater areas around the world, fossils from 120 million years ago have been found in Europe. The body is covered with diamond-shaped hard scales, which are very hard, and the mouth of most species is pointed like that of a crocodile. Feeding water temperature 20-26 ℃, water quality requirements are not strict. The bait includes small live fish, fish meat, water earthworms, etc., which are easy to keep. It is difficult to breed in the aquarium. Lepisosteidae (Lepisosteus) is a collective name for the large fish of the genus Lepisosteus, which is produced in North or Central America. It is closely related to the bowfin fish and belongs to the Holostei. It mainly inhabits freshwater, but some species can descend into semi-saline or even brackish water. It often floats like a log in slow-moving water to bask in the sun and breathe atmospheric air. The two palates and face form a beak with sharp teeth, and the body is covered with diamond-shaped shiny and thick hard scales. Sparrow eels have lived in Europe and North America since the Eocene, and one reason they have survived to this day may be that their large, pale green yolk-filled eggs are highly toxic. Sparrow eels lay their eggs in shallow water in the spring, and after hatching the young grow so quickly that they start out feeding on Minnow fish and soon become such voracious predators that measures have to be taken to reduce their numbers. The teeth are needle-like, arranged in several long rows, and are adapted for the plundering of prey. Long-nosed sparrow eels (L. osseus) are found in the southern United States and have extremely long, pincer-like muzzles. The blunt-nosed alligator eel (L. spatula) grows to about 3 meters (10 feet), making it one of the largest species of freshwater fish, and has a broad, short muzzle. Sparrow eels are edible, but are almost never eaten in the central and northern United States. It is sometimes dried with its hard scales, and its scales are sometimes used to make ornaments. gar (or garfish, garpike) is often used to refer to the palatine needlefish (needlefish; especially in Europe), while in Australia it is used to refer to the hemiramphus (halfbeak), which is proximal to the palatine needlefish. Sparrow eels
The order Sparrow eels (Lepidosteiformes) is an order of 1 in the subclass of the order Scleractinia, the spoke-finned fishes. There are only seven species of fish in two genera of one family, all of which live in freshwater rivers and lakes in North America and the Caribbean islands. An ancient fish species with fossils dating back to the Permian era, the Sparrow eel order is covered with diamond-shaped hard scales, has a long mouth with sharp teeth, and is a large, ferocious fish, carnivorous, with a posterior dorsal fin and rounded caudal fin, the longest of which has been reported to be up to 6 meters long. The flesh of the sparrow eel is edible, but the eggs are poisonous.

The finch eel, there are currently found in more than a dozen species, the most important feature is that the body is covered by diamond-shaped hard scales, scales are very hard, known as bone scales; the tail is rounded, is unique to the ancient species of round tail; most species of the mouth is pointed as a crocodile, the muzzle is longer, and the teeth are developed and sharp. The finch eel appeared very early, flourished in the Jurassic and early Cretaceous, distributed in freshwater areas around the world, and now only the finch eel
Survival in North America near the Mississippi River, the main place of origin is North America. Fossils have been found in Europe from 120 million years ago, the same time as the fossils of the Archaeopteryx, but it is estimated that the finch eel lived 150 million years ago. The finch eel does not reproduce very well, but the survival rate of its young is quite high, which is one of the main reasons why the species has survived so well to the present day. It can breathe through its swim bladder, which is connected to its esophagus, and in an oxygen-deprived environment, it swallows air into its swim bladder to breathe, so it can survive for a short time on land. No finch eels have been found to survive in our mainland waters. Most species have a sharp mouth like a crocodile, a long muzzle, and well-developed sharp teeth.

Because of its ferocious nature and strong survival ability, if it is allowed to reproduce locally, it will cause great harm to the local fisheries. Its presence in natural waters is a very dangerous thing, with a predominantly carnivorous diet, it is highly likely to cause devastating harm to local fish.
In Guangdong, a farmer's fish pond once "mixed" into the two finch eels, the result of a month, the entire pond fish were eaten up, the degree of harm can be seen. In addition, due to the eel's eggs are highly toxic, once someone accidentally eat, may be fatal. The public should report to the fisheries department if they find finch eels or other strange species, and should not release foreign species into natural waters to avoid biological invasion and irreparable loss of local fish resources and species.

Shanghai found fierce poisonous fish sparrow eel One of the world's ten most ferocious freshwater fishes, sparrow eel, has appeared in the Hengxing River in Pujiang Town. Recently, Minhang District Fisheries Management Inspection Station law enforcement officers found this "strange fish". Experts warned that the eggs of this fish are highly toxic, the public should not eat. Sparrow eel
Reporters in Minhang District Fisheries Management Inspection Station to see, the fish body length of 42 centimeters, weighing 312 grams. The body is long cylindrical, mouth protruding forward, upper and lower jaw have bone plate, there are teeth, similar to the crocodile mouth. The body of the fish is greenish gray, the body surface has dark black pattern, the skin has a hard scale cover, the skin is firm and thick scales, the skin is rough. At present, experts have been initially identified, this "strange fish" for the living fossil fish --- eel. Eel is a kind of carnivorous fish, large food, very fierce, belonging to the world's top ten ferocious freshwater fish, in Shanghai Huangpu River basin is rare. Experts analyze, China has introduced such fish as ornamental fish breeding, and this bird eel is likely to be released from the family pet. The eggs of finch eels are highly toxic." Fishery experts reminded that the alternation of spring and summer is the spawning season of sparrow eels, such as inadvertent consumption is likely to cause poisoning, which will lead to death in serious cases. The person in charge of the Minhang District Fisheries Management Inspection Station reminded the public that sparrow eels are carnivorous animals that are different from ordinary ornamental fish. After entering the local ecosystem, if there is no corresponding natural enemy, it will pose a great threat to other fish. Therefore, if the public caught this fish, not only do not eat, also do not release. Currently, the Minhang District Fisheries Management Inspection Station has been stationed in the district to monitor the possibility of the reappearance of finch eels at any time. The public should consult the aquatic research institutes or extension research centers in the districts if they find it.
"Strange fish" veil
"Strange fish" turned out to be sparrow eels on August 16, Wenling City, Hengfeng Street, Zhu Jiayang village villagers Zheng Baofu caught the "strange fish" What kind of fish is it? Is not the local old man said "dragonfish" it?August 17, with many questions, I contacted the Wenling City Aquatic and Marine Bureau of Aquatic Extension Station Ding Li Fa stationmaster. After receiving the group photo of "strange fish", Ding Li Fa immediately contacted 郏国生, a professor of Ningbo University, who has profound research in fish classification. After the old professor checked the fish charts and related information, he initially identified the fish as finch eel. Prof. Jia Guosheng said that the sparrow eel is an ancient fish species, since the Upper Cretaceous period to the present, it is a relict species, belongs to the scleractinian hard-scaled fish, native to the Gulf of Mexico in North America and the United States of America along the rivers and estuarine waters of the Florida coast, but in ancient times it was globally distributed, the sparrow eel is a "living fossil" fish species of great value for academic research and belongs to the primitive type of scleractinian fish. The eel is a "living fossil" species of great academic research value, is a primitive hard-scaled fish.
Data
According to the data, the eel is one of the world's ten most ferocious freshwater fish, along with the nationally banned exotic species "pomfret". The typical characteristics of the eel are judged to be its pinkish-white triangular tongue; its body is covered with diamond-shaped gray scales, which are "hard and cold to the touch of the finger, like the scales of a crocodile" and will attack people. Experts believe that finch eels appear in the river is a very dangerous thing, very likely to jeopardize local fishery resources, resulting in species infringement. Sparrow eel is neither a national protected animal nor an imported fish, experts suggest that this species should not be released. Sparrow eels have a layer of diamond-shaped fish scales, looks like a warrior wearing armor as exceptionally hard, in fact, it is composed of inorganic salts, many extinct ancient fish also have such scales. Sparrow eel eggs are extremely poisonous, and inadvertent consumption by humans or other warm-blooded animals will result in death. As for the finch eel is how to appear in the river waters, expert analysis, young finch eel and grass carp is not much different, it is possible that the release of fish fry species appeared to be misplaced.
