How many legs does an animal have at most, and what are the animals with one leg?

It should have up to 8 legs.

It's a snake, and the snake's body is elongated, but it can stand up, and it's also considered a leg.

Snakes are a special group of organisms that have evolved over a long period of 100 million years and play an important role in maintaining ecological balance. Snakes are ectotherms, with a low degree of evolution, and their distribution and survival are greatly affected by climate, and they are a relatively stable and fragile biological group.

Activity characteristics

Snakes are ectotherms that change body temperature with air temperature, as snakes themselves do not have a well-developed thermoregulatory mechanism to produce and maintain a constant body temperature. The optimal temperature for snake activity is 20-30 °C, and the growth rate of snakes in this suitable range also rises with the temperature rises.

Air humidity also has a great influence on snakes, generally 50-70% is appropriate. The activity of snakes is closely related to outside temperature, humidity, light, and food. Under the influence of these external environmental conditions, there are obvious seasonal and diurnal characteristics.

— a one-legged animalBi Fang

夔 (kuí) is a one-legged monster in ancient Chinese mythology and legend. "The Classic of Mountains and Seas: The Great Wilderness Classic (The Great Wilderness East Classic)" records: There is Liubo Mountain in the East China Sea, which enters the sea for 7,000 miles.

There is a beast on it, like an ox, with a pale body and no horns, and one foot, and if it enters and exits the water, it will be stormy, and its light is like the sun and the moon, and its sound is like thunder, and its name is called Kui. Yellow Emperor.

Get it, with its skin as a drum, and with a thunder beast.

The bones, the sound of five hundred miles, to power the world.

Bi Fang is an image from ancient Chinese mythology and lives in Zhanggu Mountain. According to the "Classic of Mountains and Seas, the Classic of the West Mountains.

Notes: Bi Fang is shaped like a crane, with only one leg, red markings on its blue feathers, and a white beak.

Image evaluation. The appearance of the image of Bi Fang expresses the fear and yearning of primitive human beings for fire, and the origin of "Bi Fang" and "Bi Fang" should be discharged with the meaning of "end" and "surname". It is the origin of the "Biyue Bird" that people regard fire as a god.

In the decoration of bronzes in the late Shang and Western Zhou dynasties, the Kui dragon pattern is one of the main ornaments, the image is mostly a long strip with an open mouth and a curly tail, and the shape is suitable for the structural line of the bronze veneer, mainly with straight lines, supplemented by arcs, with an ancient and clumsy beauty.

There is no animal in the world with a single leg, except in the case of malformation.

1. At the beginning of life, a cell is a life, and slowly evolve into multicellular organisms, sponges are the most primitive and lowest multicellular animals, and the body is an asymmetrical structure. Then coelenterates such as jellyfish began to appear, dividing their bodies into two parts, called "radially symmetrical organisms", which were only divided into upper and lower parts, and could only be fixed in the water or float with the current, passively ingesting food from their surroundings.

2. The ancestors of the class Insecta are myriapod animals, similar to horses. Because there are too many legs that are useless, some of the legs are evolved into appendages such as mouthparts, leaving six legs, which is enough.

3. Marine mammals, dolphins, walruses, sea lions, seals, and whales do not have legs in the true sense of the word, or have evolved into flippers. If we only look at terrestrial mammals, I personally think that it is because of the characteristics of vertebrates, that "two forelimbs and two hind limbs are sufficient".

Legless animals are earthworms, snakes, snails, snails, shellfish, mussels, whales, sharks, dolphins, etc

1. Earthworms::

Earthworms, also known as earth dragons, are terrestrial invertebrates of the phylum Annelids.

Earthworms are one of the annelids, there are more than 3,000 species of earthworms in the world, and there are more than 200 species in China. There are ringworms, Aisheng worms, heterolip worms, dura worms and other varieties widely distributed throughout the country.

2. Snakes: Snakes are a class of animals under the phylum Chordates and Reptiles.

The body is elongated, divided into three parts: head, trunk and tail, without limbs or claw-like hind limbs on both sides of the cloaca transversely lobed by lower snakes; Covered with scales; The head is of a variety of shapes, with nostrils located on the snout side, but the lifelong marine serpentidae species live on the back of the snout.

3. Snails: Snails refer to all terrestrial species of the class Gastropoda.

In general, Western languages do not distinguish between aquatic snails and terrestrial snails, and in Chinese, snails only refer to terrestrial species, while snails in a broad sense also include giant shield slugs. The snail is an animal that includes many different families and genera. Feeds on plants and lays eggs in the soil or on trees.

1.Spider: Brother takes the spider's body and head together, and has only eight legs.

2.Snakes: Snakes have no legs and only a long body that relies on the scales on their abdomen to reduce friction as they crawl.

3.Octopus: The octopus also has no legs, only one head and eight tentacles with the envy.

4.Turtles: Turtles also have only four legs, but their legs are hidden under their heads and only stick out when crawling.

5.Scorpions: Scorpions also have only four legs, but their legs are relatively slender and can usually only be seen when crawling.

6.Centipedes: Centipedes have many legs, but they all grow underneath their bodies, so they appear to have only one leg.

7.Crabs: Crabs have eight legs, but they have shorter legs that are usually only visible when crawling.

8.Crayfish: Crayfish also have four legs, but they have shorter legs and are usually only seen when crawling.

9.Dragonflies: Dragonflies have six legs, but they have relatively slender legs that are usually only seen when flying.

10.Cicadas: Cicadas also have six legs, but they have shorter legs that are usually only visible when crawling.

In conclusion, there are many species of one-legged animals, but they all have different morphologies and characteristics.

One-legged animals include ostriches, mammals, insects, spiders, and many arthropods.

Starfish are 5-legged and are the most representative group of echinoderms with structural physiology. The body is flattened, mostly symmetrical with five radiations, and the demarcation between the body disc and the wrist is not obvious. When living, the mouth faces down, and the mouth faces up.

The ventral side of the wrist has a step groove, and the groove protrudes from the tube foot. The plates of the endoskeleton are connected by connective tissue and are flexible and flexible. The body surface has spines and fork spines, which are protrusions of bones.

The membranous vesicular protrusions protruding from between the plates of the bone are covered with epithelium, lining the epithelium of the body cavity, and its inner lumen is connected to the secondary body cavity, called the skin gills, which have the effect of respiration and the diffusion of metabolites to the outside world. The water pipe system is well developed. Ontogeny of transfeathered brachial larvae and brachycarpal larvae.
