Factual Statements about Spiders and Arachnids

1. For spiders, the respiratory system is typically represented by lung sacs or tracheae (or both). Spiders have a unique respiratory system that differs from other arthropods. They do not have lungs like mammals do, but instead, they have specialized structures called book lungs or tracheae. These structures allow spiders to extract oxygen from the air and distribute it throughout their bodies. 2. Arachnids have excretory systems represented by green glands. The excretory system of arachnids, including spiders, is composed of specialized glands called green glands or coxal glands. These glands help remove waste products from the arachnid's body. However, it is important to note that not all arachnids have green glands; some have other types of excretory organs. 3. Spiders have extraintestinal digestion. Spiders have a unique method of digestion called extraintestinal digestion. They do not have a separate stomach or intestines like humans do. Instead, they inject digestive enzymes into their prey and then suck up the liquefied contents. This process allows spiders to break down their food externally before absorbing the nutrients. 4. The abdomen of spiders is divided into segments. The abdomen of spiders is divided into distinct segments. This segmentation is visible externally and helps provide flexibility and mobility to the spider's body. The number of segments can vary depending on the species of spider. 5. Spiders have one pair of antennae. Unlike insects, spiders do not have antennae. Instead, they have specialized sensory organs called pedipalps, which are located near the mouthparts. These pedipalps serve various functions, including sensory perception, mating, and capturing prey. Spiders typically have two pairs of pedipalps.
