Invertebrates, crabs are arthropods. As the name implies, the limbs of this animal, that is, legs, are segmented. The Arthropoda is generally divided into four classes: Insecta: The body is divided into three major parts: head, thorax, and abdomen. Adults have three pairs of legs and two pairs of wings, and breathe through the spiracles on the abdomen. Insecta is the largest class in the Arthropoda and the most numerous animal on Earth. Common ones include locusts and crickets. Crustacea: There is a cephalothorax and abdomen. Such as crabs and shrimps. The abdomen of the crab is retracted under the cephalothorax, commonly known as the navel. The largest arthropod in the world is in China, called Chelicerae (ao second tone), which is a close relative of the ancient trilobite. Arachnida: 8 legs. For example: spiders, scorpions.
