What animals have horns on their heads and thorns on their bodies

There are several main groups of animals with horns on their heads: cattle, deer, sheep, some amphibians and mammals. Generally speaking, these animals are inferior animals in nature, with a docile personality, and in order to deal with powerful predators or carnivores, they have evolved hard and sharp horns to defend themselves.

There are many species with horns, such as snails and other species with "antennae" in the phylum Mollusc, species such as the insectoid horned beetle in the phylum Arthropoda, and and bony horns such as cattle and sheep in the phylum Chordates.

Cattle animals have horns on their heads, and usually male and female animals after 1 year old have a pair of thick horns on their skulls, and the shape of the horns varies from one to the other.

Bovini, a family of cattle, is a family of cattle subfamily. Bison with chromosome number 56 and 60 pairs of cattle, large cattle with chromosome 58, crossbred with fertile offspring, mammals, prone to Robertsonian translocation (centromerese fusion) to change chromosome number to reduce fertility, herbivorous, some species are domestic animals (including cattle, cattle, buffalo and yak). The body is stout, and some bulls have a pair of horns on their heads.

Cattle help humans in agricultural production.

The horned amphibian on the head is the horned crocodile, it mainly lives in the late Triassic, the body length is about the same as the current crocodile is only 5 meters long, but the height can reach meters, and the enemy mainly relies on its sharp and strong teeth and horns, with a strong defense and strong attack ability, but the reason for its extinction is still unclear.

Horned crocodiles mainly lived in the late Triassic period, and their body length was about the same as that of today's crocodiles, only 5 meters long, but the height was very high enough to reach meters, and the whole body was covered with quite hard carapaces, and there was even a pair of 45 cm long sharp horns on the head, so what did this do to the horns.

The horned crocodile, also known as the genus Streptocrocodile, is an extinct archosaur reptile. They lived mainly in the Late Triassic United States, while the horned crocodiles that lived in Africa and South America probably lived 100 million years ago, and they were similar in appearance to modern crocodiles, but they were quite irritable, with super-hard carapace and a pair of horns that they didn't know what to do.

Answer: Hello, there are 105 species of horned animals in the world. Horn is a product of the epidermis and dermis of the mammalian head. Horns can be divided into five types: cave horns, solid horns, pronghorned antelope horns, giraffe horns, and epidermal horns.

1. Cave angle: It is composed of the bone heart and the keratin sheath, which is commonly called the horn, which is born on the frontal bone in pairs, and does not replace it throughout its life, and has a growing trend. The horns of the cave are endemic to bovids.

There are 49 genera and 59 species of cave horns. 2. Solid angle: it is a bifurcated bony angle without a horn sheath.

The newborn horn has tender skin on the core of the bone, which is commonly known as the fluffy horn. This is characteristic of cervids. There are 17 genera and 38 species of ceratozoa.

3. Horn antelope: It is a horn type between the horn and the antler. The heart of the bone is not bifurcated and the horn sheath has a small fork, and the bifurcated horn sheath has fused hairs, and the hairy horn sheath is replaced after the reproductive period of each year, and the bone heart does not fall off.

This horn type is unique to male pronghorns. At present, there is only one species of pronghorn left. 4. Giraffe antlers:

It is composed of ** and bones, and there is almost no difference between ** on the heart of the bone and ** on the rest of the body. There are 2 species of giraffe antlers. 5. Epidermal corners:

It is composed entirely of hairy keratin fibers of the stratum corneum of the epidermis, and has no bone components, which is unique to the Rhinoaceae family. There are 5 species of epidermal horns.

The spine is a common defense device, and there are many animals in nature that have the characteristics of thorns. Here are some common examples of animals that may have spines on their bodies:

1.Hedgehog: The hedgehog is one of the most well-known animals with spines. Their backs and sides are covered with hundreds of sharp, hard spines that are used to protect themselves from predators.

2.Sea urchins: Sea urchins are marine creatures that have a hard shell and thousands of long, fragile spines. These spines can be used to protect them from predators.

3.Squirrels: Some species of squirrels, such as tree squirrels and African giant squirrels, may have spiny hairs on their backs and tails. These prickly hairs can be used to protect oneself from predators.

4.Manta rays: Manta rays are a type of fish that live in the deep sea, and they have long, sharp spiny fins and spines that are used for predation and defense.

5.Poison dart frog: A poison dart frog is a small venomous frog that may have spiky toothed plates. These spiky toothed plates contain toxins that are used to protect themselves from predators.

Please note that the causes and forms of thorns on different animals will also vary depending on the yozakura. Some spines are used for defense and protection, while others are used for predation and hunting. In addition, there are other animals that may have spiky structures on their bodies, depending on the species and environment.

1.Hedgehogs have thorns on their bodies.

2.Hedgehog is a general term for a group of small mammals in the family Hedgehogidae of the order Hedgehogs. The body is fat and short, the claws are sharp and curved, the eyes are small, the spring hair is short, the body is covered with short and dense spines, the back and sides of the body are covered with spines, the mouth is pointed and long, and the tail is buried and short.

3.Different subspecies have slight differences in coat color in different regions. Because its body is wrapped in a layer of sharp prickly hair, it is named, also known as hedgehog, hedgehog rat, hedgehog rat, hedgehog, etc.

Hedgehogs, sea urchins, spiny dolphins, porcupines, spiny-crowned starfish, porcupine fish, echidnas, Australian magic lizards, hedgey moths, armadillo ring-tailed lizards, etc. Hedgehog: When frightened, its head is bent towards the ventral surface, its body curls up into a ball, wrapping its head and limbs, and erecting spines all over its body to protect itself.
