What is a Spider?
Spider consists of two body segments: cephalothorax and abdomen, eight-legged and are predatory arachnids. About 50,000 species of spiders can be found all over the world(except Antarctica). Spider body divides into two regions: cephalothorax and abdomen. Spider has one to six pairs of simple eyes. Spider has four pair of appendages or legs that connected to the cephalothorax. Cephalothorax of spider consist of brain, stomach, mouth fangs, and glands, which produce poison. The abdomen of the spider consists of gland type called spinneret from which silk released to outside. To stick their body to the web, they secrete oils. The hairs which are present to the legs of the spider are sensitive to smell and vibrations. It’s every leg has six joints. So, they have 48 knees. The spider used to feed on liquid food. That’s why they have a tiny gut. Most of the spiders are predators who inject poison to kill their prey, though herbivorous spiders are present as well. Spider undergo incomplete metamorphosis. There are three stages of their life cycle as egg, larva, and adult.
What is an Insect?
Insect possesses six legs and one or two pairs of wings and is small arthropods. Around 6-10 million insects found in all over the world. Most of them live in terrestrial environments. Body divides into head thorax and abdomen. They have one pair of compound eye and a pair of antennae. Characteristically, two pairs of wings connected to the thorax. Insects have six legs. The body of the insect covered with an exoskeleton, which is made up of chitin. Insects feed on animal material as well on plants. Feeding occurs through three types; chewing, sponging, and sucking. Chewing insects have mandibles, labium, and maxilla as their mouthparts. Respiration in insects occurs through the trachea. Insects undergo complete metamorphosis. Stages of the life cycle are an egg, larva, pupa, and adult. Insects typically move through walking, flying and sometimes by swimming. Water spiders are capable of walking on the surface of the water.
ConclusionAbove discussion concludes that spider consists of two body segments: cephalothorax and abdomen, eight-legged and predatory arachnids whereas insect possesses six legs and one or two pairs of wings and are small arthropods.
