Elephant tortoise
(name: Chelonoidis nigra) is the largest tortoise in existence. Privately owned for Ecuador I Galapagos Islands.
Because the ecological environment of the islands in the Galapagos Islands is significantly different, the tortoises of different subspecies have different morphologies, opening up Darwin's theory of "independent evolution" thinking. An adult tortoise is 1.2 meters long, weighs up to 300 kilograms, and is estimated to be 200 years old.
The Galapagos tortoise is a herbivore, and its food includes giant palms, grass, leaves, moss and berries. A black turtle eats an average of 32-36 kilograms (70-80 pounds) of food per day, but absorbs less nutrients due to a less efficient digestive system.
Tortoises get most of their water from plant dew and sap, so they can go without water for a long time. They can also endure for up to 18 months without eating or drinking; and when they are thirsty, they can drink large amounts of water quickly and store it in their bladders and hearts, making them useless for eternity. Drink more water. On drought-stricken islands, giant tortoises licked dew from boulders during the Qing Dynasty, and many rocks have pits formed by this activity over generations.
Turtles are cold-blooded animals (cold animals), so they will bask in the sun for 1-2 hours to absorb the heat of the sun, and they will actively look for food after dawn. They sleep 8-9 hours a day, mostly in the early morning or in the evening. At the same time, they are walking at a speed of 0.3 kilometers (0.2 miles) per hour.
On larger, wetter and low-altitude islands, seasonal migrations will occur among turtles. During the dry season, they will migrate to grassland areas with higher altitudes (610 meters). Unique roads have been around for a long time, creating a good way to walk, and the bushes passed by black turtles are called "black turtle roads".
On cold nights, Galapagos tortoises will rest in muddy and rain-generated pools, probably because they need to regulate their body temperature and expel parasites. Some turtles also rest under overhanging rocks.
Galapagos tortoises are only scattered on 9 small islands in the Galapagos Islands in South America. There are 12 subspecies in total, 10 of which still have individuals surviving in the wilderness.Another subspecies (Pinta Island subspecies) has only one male turtle named "Lonesome George".
