The living habits and characteristics of turtles

Tortoise is a reptile evolved from the carapace. Tortoise was first seen in the early Triassic period. It has a wide variety of species, long life and convenient to raise. Therefore, it is a good partner of human beings. However, many people do not understand him, so let us know the living habits and characteristics of tortoises together!

Living habits of turtles

1, turtle is omnivorous animals, turtles in the wild, usually small fish, occasionally eat water plants, large turtles, snapping turtles sometimes eat ducks. The Galapagos tortoise feeds on cacti.

2. There is a reason why the turtle's back armor is arc-shaped. According to experiments, it is found that the arc of the same volume can bear twice the weight of other objects. It is for this reason that the shell of the turtle has not changed since the age of dinosaurs.

3. The male and female of young turtles depend on the temperature. If the incubation temperature is above 36.5 degrees, it is usually female; below 36.5 degrees, it is usually male. Therefore, if the upper part of a nest of eggs is exposed to more sun, it will be female; and if the sun is less exposed below, it will be male.

Tortoises also hibernate in subtropical regions, but because the weather in subtropical regions is warmer, this hibernation of turtles is not necessarily sleeping, but it changes to eat less and move less.

Tortoises are cold-blooded animals, so turtles like to bask in the sun and need the sun to maintain a certain temperature to help digestion. It also increases vitamin E and eliminates some of the microbes on the carapace.

6. Distinguish between male and female. The first is to see the abdominal carapace, male abdominal carapace is concave, female abdominal carapace is flat. The second is to look at the anus, male anus in the outer part of the carapace, female anus in the carapace inside.

Encounter enemies or frightened, they will head, limbs and tail into the shell.

2, life is very long: how long the life of the turtle, there is no final conclusion, generally speaking can live for 100 years, according to the relevant textual research there are more than 300 years, some even more than a thousand years.

3. Slow growth: The growth of turtles is relatively slow. Under normal conditions, the growth rate of female turtles is as follows: the weight of first-year turtles is about 15 grams, the weight of second-year turtles is 50 grams, the weight of third-year turtles is 100 grams, the weight of fourth-year turtles is 200 grams, the weight of five-year turtles is 250~250 grams, and the weight of sixth-year turtles is about 400 grams. Male tortoises grow slowly, and the largest sexually mature individual is generally below 250 grams.

4, strong hunger tolerance: turtle hunger tolerance is strong, even if the fasting months are not easy to starve, disease resistance is also strong, and the survival rate is high.
