Turtle, the common name of turtle, belongs to the family of soft-shelled turtle and tortoise belongs to the family of turtles. The shell of the turtle is softer and has no pattern on the shell, which is smooth to the touch. Turtles have a hard shell with various patterns on it, and when in danger, their limbs will immediately retract into their shells, while turtles will not.

The specific differences are as follows:

1, the genus is different: soft-shelled turtle belongs to the family of soft-shelled turtle, tortoise belongs to the family of turtles.

2, the shell is different: the shell of the turtle is softer, no pattern on the shell, feel smooth. The shell of the turtle is hard, and there are many kinds of patterns on the shell.

3, different character: the turtle's character is more ferocious, easy to bite people, the turtle character is more gentle.

4. Turtles are very timid, and when they are in danger, they will immediately retract their heads and limbs into their shells, while turtles will not.

Turtle's lifespan is usually around 30 to 60 years.

The turtle is a metamerism, amphibious, and breathes with its lungs, so it is important to have a sufficient area of land beach around or in the center of the turtle pond for it to carry out land activities. The turtle's living habits can be summarized as "three happy and three afraid", i.e. quiet and afraid of shock, like the sun and afraid of the wind, like clean and afraid of dirty.

The turtle is sensitive to the sound of the surrounding environment, as long as there is a little movement around, the turtle can quickly dive into the silt underwater, so the environment of the turtle farm or turtle pond must be kept quiet. If the turtle is often frightened, it will be unfavorable to its growth and reproduction.

The lifespan of different species of turtles varies. Some turtles can live for more than 100 years, while others can only live for about 15 years.

Sea turtles can live up to 152 years. Although a turtle's age can be determined in a number of ways,? but so far,? the only way to accurately determine the age of a turtle is through year-by-year feeding records. Observational records of turtle lifespans often take a long time, even longer than the lifespan of the researcher, and require long periods of continuous observation over several generations.

While turtles have a long physiological lifespan, their ecological lifespan is generally shorter. The ecological lifespan of the animal can be explained by analyzing it from the perspective of its survival environment. Tortoises are extremely resistant to starvation, which is related to their lower metabolic rate. The average tortoise can still continue to live without food or drink for a month or even several months. This extraordinary ability of turtles also contributes to an extended ecological lifespan under conditions of natural food shortage. Nonetheless, the average wild tortoise, threatened by disease or natural predators due to frequent lack of food, generally lives 50-70 years,? those exceeding 100 years are in the minority.
