The turtle is a long and flat reptile with a bulging back, short limbs, and a hard armor. Mainly feeds on plants, small fish, and shrimps. When people mention turtles, they always mention the saying "a thousand-year-old turtle and an eighty-thousand-year-old turtle". This shows that the turtle has a long lifespan and is also known as the "old longevity star". So why do turtles live so long? Through research by zoologists from cytology , anatomy , physiology and other aspects, it is believed that the number of generations of a turtle's cell reproduction determines the length of the turtle's lifespan. The more its cells reproduce, the longer its lifespan, and vice versa. is shorter. Animal anatomists even removed a turtle's heart and it was still beating normally for 48 hours. This also reflects that strong heart function is one of the reasons why turtles live long lives. In addition, the number of irregular polygons on the left and right sides of turtle shell is equal, which also shows that the magnetic field of the turtle is evenly distributed. Moreover, there is no excess fat in the body and less extracellular fluid, so it can prevent external electromagnetic fields from destroying the balance of its internal electromagnetic fields. The turtle's longevity is also closely related to its slow movement, slow metabolism, and resistance to hunger and drought.
