What are the living habits and characteristics of turtles?

Turtles are reptiles that evolved with a shell as their central feature. Turtles first appeared in the early Triassic period. They come in a great many species, live a long time, and are easy to keep, which makes them great companions for humans. However, many people do not really understand them, so let us get to know the living habits and characteristics of turtles together!
Living habits of turtles
1. Turtles are omnivores. In the wild, turtles usually eat small fish and occasionally nibble on aquatic plants. Large turtles, such as snapping turtles, sometimes even eat ducks. The giant tortoises living on the Galapagos Islands feed mainly on cacti.
2. There is a reason the turtle's shell is arc-shaped. Experiments have found that an arc-shaped body of the same volume can bear twice the weight of other shapes. It is for this reason that, since the age of the dinosaurs, the turtle's shell has not changed much.
3. Whether a hatchling turtle is male or female is determined by temperature. If the temperature during incubation is above 36.5 degrees, it is usually female; below 36.5 degrees, it is usually male. So the upper part of a clutch of eggs gets more sun and will be female, while the lower part gets less sun and will be male.
4. Turtles also hibernate in subtropical regions, but because the weather in subtropical regions is relatively warm, this hibernation is not necessarily all about sleeping; they simply eat less and move less.
5. Turtles are cold-blooded animals, so they like to bask in the sun. They need the sun to maintain a certain temperature to help with digestion. It also helps them produce vitamin E and eliminates some microorganisms on their shells.
6. Telling males from females. First, look at the plastron: a male's plastron is concave, while a female's plastron is flat. Second, look at the cloaca: a male's cloaca is outside the edge of the carapace, while a female's cloaca is inside the edge of the carapace.
Characteristics of turtles
1. Very varied diet: Turtles are semi-aquatic, semi-terrestrial reptiles. They mainly live in rivers, lakes, reservoirs, ponds and other waters. During the day they mostly stay in the water, and when the summer heat is intense they gather in groups to look for shady spots. They are gentle in temperament and do not bite or fight each other. When they encounter enemies or are frightened, they retract their head, limbs and tail into their shell.
2. Very long lifespan: There is still no definitive answer as to exactly how long turtles can live. It is generally said that they can live 100 years, and according to some research they can live more than 300 years, with some even exceeding a thousand years.
3. Slow growth: Turtles grow relatively slowly. Under normal conditions, the growth rate of female turtles is as follows: one-year-old turtles usually weigh around 15 grams, two-year-old turtles 50 grams, three-year-old turtles 100 grams, four-year-old turtles 200 grams, five-year-old turtles 250 to 250 grams, and six-year-old turtles around 400 grams. Male turtles grow slowly, and the largest sexually mature individuals are generally under 250 grams.
4. Strong tolerance of hunger: Turtles have a fairly strong tolerance of hunger. Even after being deprived of food for several months, they are not easily starved to death. They also have strong disease resistance and a high survival rate.
