Goldfish, eels, whales which are not fish

1. Whales are not fishes, whales belong to large mammals, and fish belong to oviparous, whales breathe with lungs, and fish breathe with gills.

2. In the past, people thought that whales were fishes because they were shaped like fishes, so they called them whales. In fact, whales are large mammals that live in the ocean. There are many types of whales, and the blue whale, which is often seen in pictures, is the largest animal on earth, with a body that can grow to more than 30 meters long and weigh more than 180 tons, and the weight of 30 elephants combined.

3. The biggest difference between whales and fish is that whales have nostrils like humans and use their lungs to breathe, while fish use gills to breathe; The whale's ** is smooth and has no scales, and fish generally have scales; Whales are warm-blooded and fish are cold-blooded; Fish are oviparous, and whales give birth to calves directly.

4. Whales do not foam, but fish do.

Goldfish are, whales are not. Whales are mammals.

Whales may appear to be fish, but they are not. Rather, mammals. And goldfish are definitely fish.

Are goldfish and whales fish? Whales are not fishes but mammals.

No, because whales are mammals, give points, grin, and grin

Although H fish has the word fish, it is not a fish, but a mammal, and it has many characteristics that are very different from fish, for example, ordinary fish swing their tail fin from side to side to make their body move forward, while whales swing their tail fin up and down.

Whales are mammals, the largest animals in the ocean, and the largest animals in the world, in fact, not real fish, but a fish-shaped vertebrate, more than 50 million years ago, the ancestors of modern whales left the land and entered the vast and boundless sea, and then after a long time, it gradually evolved into the current state, all over the world's oceans.

Not whales are evolutionary from the previous before, the previous before, the previous before. It lives on land!

Whales are not fish, they belong to the family of mammals.

No, whales are mammals.

Not fish, mammals.

Most of them live in the ocean, and only a few species inhabit the freshwater environment, and their body shape is very similar to that of fish, and their body shape is streamlined, suitable for swimming, so they are commonly known as whales, but this similarity is just a convergence phenomenon in biological evolution. Because cetaceans have the characteristics of viviparity, lactation, constant temperature, and respiration with lungs, they are completely different from fish, so they belong to mammals. Whales generally have a heartbeat of 9 to 10 beats a minute.

There are several reasons why a whale is not a fish:

1. Whales are viviparous, and fish are oviparous;

2. Whales breathe with lungs, and fish breathe with gills;

3. Whales are homeothermic animals, and fish are cold-blooded animals. Four: the whale is a mammalian ceta, a ceta, a phylum of mammalian cetams, and a fish is not a mammal at all, but a subphylum of vertebrates, and cannot breastfeed; Five:

Whales can only dive for 10 to 45 minutes, while fish can't do without water. Six: Whales have fin-shaped forelimbs, completely vestigial hind limbs, and some only have fins on their backs, and the fins are complete.

Seven: The whale moves forward in a way that swings its tail up and down. Most fishes swing their tail fins from side to side to move their bodies forward.

No, the Japanese don't have a character yet.

Goldfish is an ornamental fish, while whales are the largest known mammals in the world, usually living in the oceans and often lurking in deep sea areas.

Goldfish originated in China and is also known as "golden crucian carp", which is similar to carp. But it has no whiskers and is an ornamental fish that evolved from crucian carp. There are many varieties of goldfish, the color is red, orange, purple, blue, ink, silver, five, etc., divided into four strains: culture, grass, dragon, and egg.

In the 12th century, the genetic research of goldfish domestication began, and after a long period of cultivation and continuous optimization of varieties, goldfish from all over the world are directly or indirectly introduced by China.

Whales belong to the phylum Chordates, subphylum Vertebrates, Mammalia, and Euzos, which contain about 98 species of viviparous mammals living in oceans and rivers. There are more than 30 species in the waters of Laoqing China. All species of cetaceans inhabit the ocean, with the exception of a few that live in freshwater [1].

Cetaceans are a species of mammals that live in water.

It has the same physiological characteristics as terrestrial mammals, such as breathing with the lungs, viviparity, etc., and has some special physiological structures that have evolved to adapt to the aquatic environment. Although the whale has the word fish, it is not a fish, but a mammal, and it has many characteristics that are very different from fish, for example, ordinary fish swing their tail fin left and right to make their body move forward, while whales move their tail fin up and down. They use their flippers at the tip to maintain balance and control their forces, and some whales have fins on the upper end of their backs that keep their bodies vertical!

Goldfish is a popular ornamental aquatic domestic pet, goldfish bright color, beautiful body, ** low, easy to take care of, easy to raise, deeply loved by the majority of pet lovers.

One large, one small; One in the sea and one in freshwater; One viviparous, one oviparous.

Whales are large whales that live in the ocean, and the largest can weigh up to 150 tons, which is irreversible.

Raised at home, as for the goldfish, the volume is not large, the color is colorful, all kinds of unique shapes are very good-looking, suitable for feeding in the fish tank in the living room at home, and it is an active atmosphere added to the living room.

Goldfish are smaller than whales, goldfish are grown in freshwater, domesticated fish! Whales grow in saltwater!

Goldfish is an ornamental fish that is domestic. Whales are the largest known mammals in the world, and they usually live in the oceans and often lurk in deep sea areas.

Whales are in the ocean.

A super-large animal, the whale can reach a body length of more than 1 30 meters. Unlike other fish in the ocean, whales are very large and do not have the appearance of ordinary fish. Whales are not fish, but mammals.

Goldfish is an ornamental fish that is domestic. Goldfish are oviparous animals and are fish;
