1. What is this fish called? Please provide detailed information, thank you!

The fan-shaped ray, also known as the devil fish.

This is the underside of a juvenile ray, a translucent, ghostly-looking ray. The most common ray in British seas, the ray can grow up to four feet long and has a spiked back.

180 million years ago, rays were the same species as sharks, but in order to adapt to life on the seabed, they hid their bodies in the sand on the seabed for a long time, and gradually evolved into their current appearance.

The body of the manta ray is surrounded by a circle of fan-like pectoral fins. The caudal fin is degenerate and looks like a thin and long whip. The manta ray moves forward by the wave-like movement of the pectoral fins. The manta ray usually hides in the sand and suddenly attacks when two shellfish, crabs and shrimps approach. Their teeth are like mortars and can grind anything. There is a poisonous red thorn on the back, which can kill people if they are stabbed.

There are many different types of rays, with more than 100 species found worldwide. Rays are very similar to redfin rays in that they have flat bodies. They are found in shallow waters in all temperate and tropical zones of the world, except in the South Pacific and along the northeastern coast of South America. Common gray rays can grow to be over 2 meters in length. Young rays feed on animals that live on the seafloor, such as crabs and lobsters. As they grow older, they mainly hunt for mollusks, such as squid. When hunting, rays hunt mainly by smell. While lying on the seafloor, rays use a special closed-mouth breathing method to try to avoid inhaling mud and sand. When rays breathe, water is drawn in through pipes on the top of their heads and then flows out through the gill slits on their ventral sides.

5. What is this fish called?

As shown in the picture, it is still small. The scientific name of the knife fish and anchovy is

Family Engraulidae Genus Coilia Fish

The picture below shows Coilia mystus, commonly known as anchovy, roasted seed fish, seed anchovy, seed anchovy, Maqi fish

The head is short, the snout is short and round. The mouth is large and inferior. The mouth cleft is oblique. The maxilla extends backward to or beyond the base of the pectoral fin. The lower edge is finely serrated. There is a row of velvety teeth in both jaws, and there are small teeth on the vomer and palatine bones. The body is elongated and very laterally flattened, with a high front part and gradually lower towards the back, forming a sharp knife shape. The front part of the base of the dorsal fin is convex and oblique to the head and tail. The dorsal margin is wider than the ventral margin, and the ventral margin is wide and narrow in an arc shape. The head is slightly small and laterally flattened, and the snout tip is pointed. The mouth is large, inferior, and slightly obliquely cleft. The upper jaw is longer than the lower jaw, and the posterior margin of the maxilla exceeds the gill opening. The teeth in both jaws are small. The pectoral fins are small and laterally inferior, with 6 long filamentous free fin rays on the upper part, and the tip reaches or slightly exceeds the origin of the anal fin. The pelvic fins are short, and the origin is located below the origin of the dorsal fin. The base of the anal fin is very long, starting from the tip of the pectoral fin or slightly below the front, and the posterior edge is connected to the caudal fin, and the fin rays are within 90. The tail fin is short and has no lateral line. The back of the body is grayish yellow, and the sides and belly are silvery white. The dorsal, anal and caudal fins are light gray, and the pectoral and pelvic fins are white. The body length is generally 15-20 cm.

It is an estuarine migratory fish, usually living in shallow seas. Every spring, a large number of fish migrate from the sea to the brackish water area at the mouth of rivers to spawn. Generally, in late April (around Grain Rain), parent fish begin to come to the river mouth from the sea, but in small numbers; from early May (Beginning of Summer) to early July (Small Heat), they arrive in large numbers, spawn in brackish waters and gradually return to the sea to live. The anchovy rarely eats during its migration to the river mouth to spawn. Its food is copepods, mysids, amphipods, oysters and fish eggs.

There are many seeds in the belly, the meat is tender, high in protein, high in fat, and rich in phosphoric acid. The dried fish roe is also called Jinyinchun or Jinyin fish roe. People usually fry it and eat it. There is no need to scrape the scales or cut the belly, just take out the internal organs from the mouth. After frying, the fish bones and fish bones are also crispy, and the whole fish can be eaten. It is a good choice for summer rice and wine.

As shown in the figure, it should be

Haemulidae, Parapristipoma

The dorsal fin has 13 to 14 hard spines, the fourth spine is the strongest, and there are 17 soft rays; the anal fin has 3 hard spines and 8 soft rays. The number of lateral line scales is 55 to 57. The body length can reach 60 cm.

Distributed in the northwest Pacific region, including southern Japan, the East China Sea, and Taiwan. A medium-sized edible fish, suitable for cooking ginger soup, and can also be used as an ornamental fish. It likes to swim in dense schools in the water layer outside the coral reef area, and is most common in artificial reefs or independent reef areas. It feeds on animal plankton.

Catfish, also known as silver carp, slimy fish, catfish, and fry fish. The distinctive features of this fish are that it has no scales all over its body, a lot of mucus on the surface of its body, a flat head and a wide mouth, and four whiskers on the upper and lower jaws.

Catfish are found everywhere in the seven continents of the world, except Antarctica. Several catfish are marine fish. This type of fish varies greatly in size, including the world's largest freshwater fish, the European catfish, which is up to 5 meters long and weighs 330 kilograms, as well as a very small parasitic catfish, which is less than 10 mm in adult size and is the smallest vertebrate. This order includes 35 families, but the classification list is still changing. There are about 2,855 species, equivalent to 1/4 of freshwater fish and 1/10 of all fish species.

The colored skirt fish is an artificially colored black skirt fish. Scientific name:

(Original color) Gymnocorymbus ternetzi, commonly known as black skirt fish

This fish likes to live in weakly acidic water with a water temperature of 23-26 degrees, a pH value of 6.5-6.8, and a hardness of 5.0.
