First, turtles are ectothermic animals, which means their body temperature is regulated by the environment. As a result, they are highly sensitive to changes in ambient temperature. Their feeding behavior, activity levels, and overall health are all influenced by the surrounding temperature. Unlike warm-blooded animals, turtles cannot generate enough internal heat to maintain a stable body temperature, so they rely on external sources to regulate it. They move between cooler or warmer areas throughout the day to maintain an optimal body temperature. For their well-being in captivity, the artificial environment should closely mimic their natural habitat. Tropical turtles thrive in temperatures between 27°C and 38°C, while temperate species prefer 20°C to 35°C. Semi-aquatic turtles usually require slightly lower temperatures. Some species can be harmed or even die if exposed to temperatures below 5°C. When the temperature drops, turtles become inactive and enter a state of hibernation. To successfully raise turtles in captivity, the environment must be kept within a suitable range. At around 10°C, turtles begin to hibernate, and when the temperature rises to about 15°C, they start moving again. Many turtles begin eating at this point. A normal feeding and activity temperature is typically set at 25°C, while 30°C is ideal for feeding, movement, and growth. In the middle and lower reaches of the Yangtze River, turtles are active from April to October, and hibernate from November to March. Second, turtles are classified based on their habitats. There are five main types: terrestrial, aquatic, semi-aquatic, marine, and benthic turtles. Each species has adapted its physical structure to suit its environment. Aquatic turtles, for example, have webbed feet that help them swim more efficiently in water, while land turtles have strong, thick limbs suited for crawling on dry ground. Sea turtles have flippers instead of legs and specialized salt glands to excrete excess salt from their bodies. Turtles can also be categorized based on their diet: herbivorous, carnivorous, or omnivorous. Most aquatic turtles are omnivores, such as red-eared sliders, while semi-aquatic species like the Chinese three-leaf turtle tend to be more carnivorous. Land turtles, such as the Burmese star tortoise, are mostly herbivores. Turtles have a remarkable ability to survive without food or water for extended periods, though they cannot live without food for years. Third, all turtles are oviparous, meaning they lay eggs. The breeding season usually occurs between May and October (except in constant-temperature environments). Female turtles lay their eggs on land, and the number of eggs varies depending on the species. Freshwater turtles typically lay 2 to 5 eggs per clutch, which are white with hard calcium shells. Egg shapes and sizes differ among species, but most are oval or round. Turtle eggs need to be placed in warm and moist areas to develop properly. Hatching depends entirely on natural light, heat, and moisture. Turtles do not guard their eggs, leaving them to hatch on their own. Fourth, water and humidity play a crucial role in the life of semi-aquatic turtles. These turtles require sufficient water to fully submerge, and many activities such as feeding, mating, and socializing take place in water. The salinity of the water should match that of their natural habitat, especially for turtles from coastal areas. Water pH levels should also be adjusted to reflect their native environment. Aquatic and semi-aquatic turtles excrete urea as a waste product, leading to significant water loss. Turtles living in drier conditions lose moisture through their skin, but they can also absorb water through it. Many turtles drink directly from pools or basins, and regular misting inside the enclosure helps them stay hydrated. The humidity in the turtle's living space should be similar to what they experience in the wild. Low humidity (below 70%) can lead to bacterial or fungal infections. Fifth, light cycles are essential for the health and breeding of captive turtles. Turtles follow a natural circadian rhythm and seasonal activity pattern, so they need consistent lighting. In temperate regions, daylight hours vary from 8 hours in winter to 16 hours in summer, while in tropical areas, daylight ranges from about 10 to 14 hours. Seasonal changes in light intensity can promote breeding in captivity. Full-spectrum lights that mimic natural sunlight, including UV rays, are recommended to support feeding and reproduction. Incandescent bulbs can provide both light and heat, but they should not be placed too close to the turtles to avoid burns. Heat lamps can be used to warm specific areas, but safety measures must be in place, and they should be positioned at least 35 cm above the floor.
