Seahorse Octopus Is the baby fish a fish?

Seahorse: Ichthyidae, sea lombera, a general term for seahorse animals, belonging to bony fish. The octopus, also known as the octopus, is the largest and most precious amphibian in the world.

Its cry is very similar to the cry of a young child, so people call it "baby fish", Amphibians What are the animals that belong to "fish"? Modern taxonomists define "fish" as a vertebrate that lives in water all its life, breathes with its gills, and swims with its fins.

Fish include three major groups such as Yuankou class, cartilaginous fish class and bony fish class, there are about 26,000 species of known fish in the world, which is a large group with the largest variety of vertebrates, accounting for about the total number of vertebrates, most of them live in the ocean, and there are about 8,600 species of freshwater fish. There are nearly 3,000 species of fish in China, including about 1,000 species of freshwater fish. So seahorses are fish, and baby fish and octopuses (without a backbone) are not fish.

It is not a fish. Seahorse: Vertebrates, ichthyidae, finned subclass, sea dragon order, sea dragon family. Octopuses are a phylum of mollusks, cephalopods. And amphibians and mammals belong to the same phylum Chordates! The giant salamander, also known as the salamander, belongs to the family of cryptogill salamanders and amphibians.

Seahorses belong to fish, octopuses belong to mollusks, and dollfish belong to amphibians.

Octopuses are molluscs. The seahorse is a member of the family Ichthyidae. Baby fish are amphibians.

As the title suggests, there are three fish species. They are :

Sharks(cartilaginous fish),Seahorse(Echinosauridae),Loaches(Cypriniformes, loach fishes).

Other non-fish.

Mammals: Whales.

Molluscs: squid, octopus, cuttlefish, abalone.

Amphibians: baby fish.

Reptiles: crocodiles.

Only sharks, loaches are fish.

None of the others!

Abalone, whales, squid, loaches.

Seahorses are fish in the sea that generally live in tropical oceans. In appearance, they have a horse-like head and a tail that resembles a monkey's tail and can curl freely, so they don't look like fish. However, seahorses are indeed a type of fish, and they belong to the class Bony Fish, which is categorically a bony fish.

They have some characteristics in common with fish, such as the fact that they use gills to breathe. For example, they swim with the help of the swing of their fins. <

A seahorse is a creature that lives in the ocean. They have a peculiar appearance, their heads are more like horses, hence the name, and their tails are more like monkeys' tails, which can bend freely and even make them wrap around the plants. It can be seen that they do not look like fish on the surface, and the most obvious feature of fish, the fins are not obvious on the hippocampus, because although seahorses also have fins, they are very small and transparent.

But in terms of category, seahorses are of the class Bony Fish, that is to say they are a class of Bony Fish.

As mentioned above, seahorses have very different appearance characteristics from fish, and they are still named after "horses", but they belong to fish from the category point of view, and they are a bony fish. This is because, although they look like horses, they have some essential characteristics that are the same as those of fish.

For example, fish breathe with gills, and seahorses breathe with gills, so if you look at them up close, you can see signs of their breathing. In addition, fish have fins and use them to swim. Seahorses also have fins, although they are small and transparent, but they can be observed if you look closely.

Seahorses have dorsal fins, pectoral fins, and so on. Seahorses also need their fins to swim. When they are moving, the fins swing very quickly, especially their tail fins.

The salamander, also known as the giant salamander, lives in the water as a juvenile and an amphibious adult, and belongs to amphibians; Sharks live in water, breathe with their gills and swim with their fins, and belong to fish; Whales live in water, are viviparous mammals, and belong to the category of mammals; Spoon-billed sandpipers belong to the family of birds; Crocodiles belong to the reptile class So the answer is: baby fish shark whale spoon-billed sandpiper crocodile b a e d c
