What are the 10+ types of land animals and their modes of movement?
The terrestrial environment is much more complex than the aquatic environment.
The Earth's climate is relatively dry. To adapt to this, land animals usually have structures to prevent water loss.
Land animals are not affected by the buoyancy of water. They usually have organs that support the body and movement, which are used for crawling, walking, jumping, running, climbing, and other forms of movement. to find food and avoid danger.
Except for animals such as earthworms, animals living on land generally have various respiratory organs located inside the body that are capable of breathing air.
Land animals have also generally evolved sensory organs and a nervous system capable of responding quickly to changesenvironmental elements.
Annelids that live on land, like earthworms, live in bags of moist, humus-rich earth. They use the cooperation of their muscles and hair to make their bodies wiggle, using dead leaves, rotting roots, and other plants to make them wiggle. move their body. Feed on organic matter. Body segmentation allows the earthworm's body to move flexibly. It has no lungs or trachea, and breathing relies on body walls which secrete mucus and remain moist at all times. The body wall of earthworms is densely covered with capillaries. The oxygen in the air first dissolves in the mucus on the surface of the body, then enters the body wall, and then enters the capillaries of the body wall. Carbon dioxide present in the body is also excreted from the surface of the body through capillaries located inthe body wall. Animal life requires appropriate temperature. Earthworms cannot maintain a constant body temperature, so they can only live in the deeper layers of the earthbag where the temperature does not change much.
Land animals and mammals. Their hairs are smooth and soft, which has a thermal insulation effect; they breathe with the lungs; their heart is divided into four chambers and has two circulation routes; their body temperature is constant; they have incisors, molars and canines; developed cranial nerves and limbs.
There are many other land animals. However, the morphological structure and physiological functions of all living beings are adapted to their living environment.
Examples of biological adaptation to the environment:
(1) Hibernation and aestivation: Hibernation of. animals are a response to the cold of winter. AEnvironmental adaptation is an adaptation to the hot, dry environment of summer.
(2) Trees lose their leaves to adapt to the cold environment or drought in winter.
(3) Carnivorous animals feed on other animals and they all have sharp claws and teeth (or beaks).
(4) Protective Color: Animals adapt to their habitat and have body colors similar to the color of the environment. The frogs in the grass are green, while those in the mud pond are yellow-brown.
(5) Alert Colors: Bright colors and markings of some animals having foul odors or bites are called alert colors. For example, venomous snakes have shiny patterns.
(6) Mimicry: The shape of appearance or color spots formed by some animals during the process of evolution are abnormally similar to those of other living or non-living thingsvants. For example, stick insects look like bamboo knots and dead leaf butterflies look like dead leaves.
