In the biological world, turtles are known for their unique structure and long history of survival. Tortoises are a group of reptiles that are distinguished from other animals by their shell-like external protective structures. Their shells not only provide physical protection, but also give them a survival advantage over predators.

The construction of the turtle model is a masterpiece of natural selection. Its hard shell is made up of two parts: the back plate and the belly plate. Back nails come in a variety of shapes and colors, and often blend in well with the environment and act as camouflage. The abdominal armor provides protection for the internal organs, and this dual protection mechanism allows the tortoise to be at ease in the face of predators. When threatened, many tortoises quickly retreat into their shells, using this unique biological structure to demonstrate their tenacious ability to survive.

The physiology of the turtle is also remarkable. They have a slower metabolic rate, which allows them to survive in resource-poor environments. Tortoises can withstand long periods of starvation and drying out, which allows them to continue to thrive even in hostile environments. Its lifespan is extremely long, and some varieties can even live to more than 100 years. This biological feature has led people to ponder the meaning of life and time.

The turtle's lifestyle is full of wisdom. Most tortoises are omnivores, feeding on aquatic plants, small insects, and fruit. They tend to adjust their diet according to seasonal changes and make full use of the surrounding resources. In addition, tortoises display a series of complex behaviors during courtship, and males will display the enthusiasm of courtship in order to attract females and promote the reproduction of the population.
