What is the animal with the most feet in the world?
The animal with the most feet in the world is the millipede, also known as the horse land. It is a terrestrial arthropod with a cylindrical or oblong body shape, divided into two parts, the head and the torso, and a pair of thick and short antennae on the head; The trunk is made up of many body segments, up to several hundred. Except for section 1 without feet and sections 2 through 4, which are one pair of feet per segment, the rest of each section has two pairs of feet, so there are many feet. In the Panama Valley of North America, there is a large horseland with 175 knots and a total of 690 feet, which can be said to be the most legged arthropod in the world.
Millipedes are not born with so many legs. The newborn larvae have only 7 nodes, the molting increases to 11 nodes at a time, and there are 7 pairs of feet; After secondary molting, it increases to 15 segments, with 15 pairs of feet; After several abnormal developments, the body segment gradually increases, and the foot also increases. Of course, there are many other species of millipedes. Some have smaller bodies, only 2 mm long; Compared to Malaysia, they have far fewer feet.
When the millipede walks, the left and right feet move at the same time, and the front and rear feet advance in turn, closely connected into a wave-like movement, very rhythmic, although there are many feet, but the action is very slow. They usually prefer to move in groups and generally live in dark and damp places, such as in piles of dead leaves or under rubble. Exclusively eat deciduous and humus; There are also a few species that eat the young shoots and young roots of plants and are pests in agriculture.
Although the millipede has no poisonous jaws and does not sting, it also has defensive weapons and skills. When it is touched, it immediately curls up into a ball, stands still, or rolls elsewhere, and then slowly stretches out and crawls away when the danger has passed. The millipede has odorous glands on its body joints that secrete a poisonous odorous liquid with an unpleasant smell that makes poultry and birds dare not peck at it.
