What are the benefits of flattened animals and what are the main characteristics of flattened animal

Flattened animals have some unique adaptations in nature, allowing them to adapt to a variety of environments.

First, flattened animals are flat, which allows them to adapt to a variety of different environments, both aquatic and terrestrial. This flat size allows them to swim freely in the water and even crawl underwater, which expands their living space.

Secondly, the symmetrical body shape of the flattened animals gives them greater adaptability. With this body size, flattened animals are better able to perceive their surroundings and respond in a timely manner. At the same time, this body type makes the functions of various parts of the body divide labor, such as the ventral surface mainly forms some digestive and motor organs, which assume the functions of movement and feeding, and the long muscles on the back have protective functions.

In addition, the appearance of flattened animals also marked a great advance in the evolutionary history of animals. They were the first trigerm-layer animals, and their appearance represented a major advance in the animal kingdom.

In summary, flattened animals have a flat body shape and symmetry on both sides, which allows them to adapt to a variety of different environments, perceive their surroundings, respond in time, and their appearance marks a major advance in the evolutionary history of animals.

Flattened animals are divided into three classes, tapeworms and trematodes that are obviously detrimental to humans and animals, but there are currently studies on planarians, from which perhaps some of the mechanisms of tissue regeneration can be inspired. In addition, it is difficult to say that it has obvious benefits for humans (of course, planarians often feed on organic matter and food residues in the water, which has the effect of purifying the water).

However, some planarians can also parasitize farmed shrimp and crabs and other animals and cause harm.

The main characteristics of flattened animals are that they live in moist places such as freshwater and oceans, have two light-sensitive pigment spots (eyespots) at the front of the body, and have cilia on the body surface partially or completely.

Begin to have a well-developed mesoderm and appear bilaterally symmetrical; With muscle tissue, the receptors are also improved, and the functions of feeding, digestion, and excretion are also strengthened. Mesenchymal tissue formed by the mesoderm.

Also known as parenchymal tissue, it fills the body between various organs and can transport nutrients and excrete waste; Histiocytes also have the ability to regenerate new organ systems.
