What animal has the largest field of view among mammals?

I personally think it is an ostrich, because the ostrich has a vision of 25 and can recognize objects within 10 km, and the ostrich can clearly see ants moving at a distance of 42 5 meters from it. Since the beginning of the Jurassic, birds have extensively adapted to the Cretaceous and evolved a variety of water and land birds to adapt to a variety of environments. After entering the new generation, due to the extinction of the terrestrial dinosaurs, the ecological status of mammals was mostly replaced by birds before they developed into large animals.

For example, the Eocene of North America should snow birds, for huge but flightless carnivorous birds, it filled the vacuum of carnivores, pheasant is a large carnivore in the Miocene of South America, it could not fly, and also filled the vacancy of the lack of carnivores in South America at that time. In addition, there are several species of flightless birds, which are often classified as walking birds. On different islands or special areas, vacancies for the lack of mammals are filled.

Notable examples include the pheasant bird in New Zealand, the native bird in Australia, and the elephant bird in Madagascar, which tragically became extinct after the emergence of humans. However, there are also some lucky birds, such as the ostrich in Africa, the European Monetary Union and Turkey in Australia, the kiwi in New Zealand and the fauna of South America, which are still surviving. The biggest common feature of these birds is the flat sternum without keel protrusion.

However, in the evolutionary process of the gradual loss of flight ability, the strong pectoral muscles used for flight and their appendages are no longer needed. However, whether these birds are similarly related remains to be explored with sufficient fossil evidence. By the way, the dodo is also a flightless land bird, but it is not a close relative of the bird, but a member of the pigeon, so it does not have the ability to run like a bird.

If you have other different ideas and views, you can share your personal views in the comment area below, if you like me, you can pay attention to it, and finally wish you all the best.

The horse has the largest field of view among mammals, its field of view can reach almost 360 degrees, and it does not have a so-called blind spot at all.

I think it's a dog, because the dog's eyes are on both sides, so the visible range is very large.

Among the mammals, the largest is the blue whale.

The average head-to-body length of adult blue whale males is 25m and that of females is 27m. The longest specimen length confirmed after the fissure. It is the largest living animal in the world.

Blue whales have a slender body with a blue-gray back with light-colored spots, and the belly is often covered with microorganisms and has a yellowish color. The head is broad and flattened, with a chevron spot on the top of the head behind the breathing hole, sometimes the boundary between the head and the body that changes color.

The abdomen of a blue whale has 50-180 folds that extend from the chin to beyond the navel and can both expand and contract. The flippers are long and blunt. The dorsal fin is relatively small and is located about three-quarters of the way back from the snout.

The broad caudal lobe has a relatively straight posterior margin and a significant notch.

Introduction to mammals

Mammals are the animals with the highest morphological structure and the most complete physiology in the animal world. Compared to other animals, the most prominent feature of mammals is that they are viviparous and their young are fed with milk secreted by their mothers. Mammals have fur to keep their body temperature constant and adapt to a variety of complex living environments.

The mammaculous animal has a well-developed brain, so it can produce more complex behaviors than other animals, and can constantly change its behavior to adapt to changes in the external environment. There are more than 4,000 species of mammals in the world, and although they are all highly evolved, they still have a lot in common.
