CATDOLL : CATDOLL: Which marine fish are herbivorous?

1. Which marine fish are herbivorous?

Herbivorous fish, such as milkfish, barracuda, bluefish, etc.;

2. Is grouper a herbivorous fish?

yes.

Grouper is an omnivorous freshwater fish that prefers to feed on plants. It is widely distributed in fresh and brackish water. In winter, it mainly feeds on algae and the rhizomes, branches, leaves, and fruits of aquatic plants. In spring, summer and autumn, it feeds on algae and the young branches, leaves, rhizomes, and seeds of some aquatic plants.

3. What kind of fish is sea elf?

dolphin

Dolphins are the marine animals closest to humans, and people affectionately call them sea elves. Dolphins are marine mammals, belonging to the Delphinidae family of whales. Like humans, they are warm-blooded, with a body temperature of about 36 degrees Celsius. They breathe with lungs and mainly feed on fish.

4. Is the manta ray a fish?

It is a kind of fish. In terms of classification, skates belong to the class Chondrichthyes, which is a type of cartilaginous fish. Their skeletons are all cartilaginous. Although some parts have a certain hardness after calcification, they are generally not comparable to bony fish. They also belong to the order Gnaphalidae. In terms of distribution area, skates are a kind of marine fish with a very wide distribution range, and they are basically distributed in the oceans of the world.

From the perspective of the body size of manta rays, the size of manta rays is not fixed. Some are relatively small, but some are relatively large. Some of them are only about 50 cm long after adulthood, and very large manta rays can reach 2.5 meters in length. The body size is not fixed and the difference is quite large. From the perspective of habit characteristics, manta rays are carnivorous fish and are carnivorous animals. They feed on surrounding mollusks, shrimps and crabs. When they hunt, they use their very sensitive sense of smell to find prey and then catch them.

5. Are shrimps, whales and fish?

Whales are not fish, they are mammals, aquatic animals. Whales and other fish have different reproduction methods. Whales are born in the womb, and each womb produces a small whale. The small fish grows through milk, while fish are oviparous and can produce thousands of eggs at a time. The small fish do not need to breastfeed. The breathing method is also different. Whales breathe with lungs, while fish breathe with gills.

6. Herbivorous plants?

Herbivory refers to one of the biological interactions, usually referring to the phenomenon that animals feed on plants. It is almost impossible to find a plant that is not eaten by animals, and among animals, from lower animals to higher animals, there are many species that specialize in eating plants.

Animals eating plants is the basis of the food chain in nature and the basic link of the food chain. The other links in the food chain depend on the existence of this link. It can be seen that all animals rely on plants for food directly or indirectly.

7. Which sea has the richest fish resources in the world?

Japan's Hokkaido fishing ground, North Sea fishing ground, Newfoundland fishing ground and Peruvian fishing ground are the four major fishing grounds in the world!

1. Hokkaido fishing grounds, Japan

Located in Hokkaido, Japan, the Kuril Current and the Japan Current meet. We know that there are many fish species where the cold and warm currents meet, which is also a prerequisite for the formation of fishing grounds. The Hokkaido fishing ground is also the largest fishing ground in the world, accounting for 25% of the catch in Japan. The main fish species include salmon, haddock, herring and saury, etc. Moreover, the seawater here has never been polluted, and the fish quality is particularly good.

2. North Sea Fishery

Located on the northeastern edge of the Atlantic Ocean, it is formed by the confluence of the North Atlantic warm current and the Greenland current. The fresh fish production here accounts for half of the world's total, providing abundant fish resources for European countries. The annual catch of the North Sea fishing grounds is about 3 million tons, accounting for 5% of the world's catch. The main fish species are herring, mackerel and cod.

3. Peruvian Fisheries

The Peruvian coastal area, located in the eastern Pacific Ocean, has a large number of plankton due to the Peruvian cold current and a large amount of nutrients such as nitrates and phosphates, providing favorable living conditions for cold-water fish. The Peruvian fishing grounds are rich in more than 800 species of fish and shellfish, including anchovies and anchovies. The catch in 1972 exceeded 10 million tons, but this fishing ground is susceptible to the El Nino phenomenon and the production has dropped sharply.

4. Newfoundland Fishing Ground

As early as 1534, it was discovered that there were abundant fish in the Newfoundland Island, Canada, North America, which is formed by the confluence of the Gulf Stream and the Labrador Current. The Newfoundland fishing grounds are rich in cod and are known as "you can go ashore by stepping on the backs of cod schools". However, due to centuries of overfishing, the fish production has dropped significantly since the 1990s, but it is still considered one of the four famous fishing grounds in the world.

8. What fish species are found in the Baltic Sea?

The Baltic Sea has a small number of fish species and numbers, mainly plaice, cod, herring, etc. The strong North Sea tides cannot reach the Baltic Sea, so there is a lack of tidal currents and small tidal waves.

The water surface was in motion due to the storm, with strong northeasterly winds causing high waves on the south coast, contributing to high coastal water levels, while the prevailing southwesterly winds contributed to the accumulation of sand dunes along the coasts of the GDR and Poland, while causing high water levels on the northern Baltic coast.

9. Ranking of herbivorous dinosaurs?

Triceratops is a genus of herbivorous dinosaurs in the family Ceratopsidae of the order Ornithischia. Its fossils were found in the Late Maastrichtian strata of the Late Cretaceous in North America, about 68 million to 65 million years ago. Triceratops is one of the latest dinosaurs to appear and is often regarded as a representative fossil of the Late Cretaceous. Triceratops is a medium-sized quadruped dinosaur, 6-8 meters long, 2.4-2.8 meters high, and weighing 5-10 tons. They have very large head frills and three horns, reminiscent of modern rhinos. Although no complete skeleton of Triceratops has been found, they are still famous for a large number of partial skeleton specimens discovered since 1887. This is also the strongest one in the ranking of the top ten strongest herbivorous dinosaurs, which can beat Tyrannosaurus Rex.

The Brontosaurus, also known as the Apatosaurus, weighed 30 tons. According to the newly discovered thigh bones of the dinosaur in Argentina, it was 4-5.5 meters tall and about 35 meters long. This dinosaur was 15,500 pounds (about 7 tons) heavier than the largest creature discovered before. However, the Apatosaurus was a gentle herbivore. The back half of its body was higher than its shoulders, but when it stood up on its heels, it was so tall that it could reach the sky. It probably lived in plains and forests, and probably traveled in groups.

Brachiosaurus is a genus of sauropod dinosaur that lived in the Late Jurassic period. Because its forelimbs were much larger than its hind limbs, Brachiosaurus was one of the largest animals that ever lived on land and one of the most famous dinosaurs of all. It was a huge herbivorous dinosaur from the late Jurassic period. Its name originally meant "lizard with a head like a wrist". An adult Brachiosaurus that was 25 meters long could lift its head to 13 meters above the ground, which is equivalent to the height of a 4-story building.

The fossil of a small dinosaur species, Fruittooth Dragon, was recently discovered by American archaeologists in Colorado. The newly discovered dinosaur was about the size of a squirrel. Studies have confirmed that Fruittooth Dragon was about 70 centimeters long, and the largest weighed only 0.9 kilograms. This dinosaur may be the smallest dinosaur known in North America. The shape of Fruittooth Dragon's teeth shows that it was an omnivore, probably eating both plants and small animals such as insects.

Hypsilophodon is an agile, small ornithopod dinosaur with sharp eyesight. It is about 2 meters long and 1 meter high at the hip. Some are as long as 9 meters, as big as Iguanodon. It has slender hind legs and a narrow and sharp beak, which is convenient for biting tree branches and leaves. There are 5 short and thick fingers at the end of the forelimbs, and sharp claws. It is inferred that it ran very fast.

The spinosaur lived in the Cretaceous period of North America about 70 million years ago. It was a herbivorous dinosaur. The name of the spinosaur means "spiny devil". The spinosaur lived in groups and in the woods. It had short forelimbs but very long hind limbs. When running, its tail was held high. It had protruding horns on its head, but they were only used for camouflage and not as weapons.

Ankylosaurus was a heavy-bodied ankylosaur, about 20 feet (6.6 m) long. It had long spikes on its head and sides, and a club at the end of its tail. Its skull had a complex nasal passage and a bony secondary jaw, suggesting that it lived in a hot, humid environment. Some evidence suggests that it may have had salt glands behind its nostrils, which allowed it to breathe moist air in dry environments.

Gigantopsaurus, also known as Massospondylus, is a genus of prosauropods that lived in the Early Jurassic (Hertanian to Plinsbachian), about 200 million to 183 million years ago. Although prosauropods are inferred to be omnivorous, Massospondylus was probably herbivorous. Massospondylus was 4 to 6 meters long, with a long neck, long tail, small head, and slender body.

10. What kinds of fish are there in Yangzonghai?

Yangzonghai Lake is rich in more than 10 kinds of economic fish, including golden threadfish, carp, black carp, whitefish, and pole fish. Hu Litao started fishing in the lake when he was 15 years old. However, since the arsenic pollution incident in 2008, the Yunnan Provincial Government announced the implementation of "three bans" in Yangzonghai Lake, namely, prohibiting drinking the water of Yangzonghai Lake, prohibiting swimming in Yangzonghai Lake, and prohibiting fishing of aquatic products in Yangzonghai Lake. He has never gone fishing in the lake again.

There are many fishermen around Yangzonghai Lake. Most of them have made a living from the mountains and the water since they were young. After the arsenic pollution incident, they can no longer catch fish, and their income is naturally affected.
