Arachnids belong to the class Arachnida, which is further divided into several orders, including Araneae (spiders), Scorpiones (scorpions), Opiliones (harvestmen), Acari (mites and ticks), and more. Each order contains different families, genera, and species, which make up the lower classifications of arachnids. These lower classifications help scientists and researchers to categorize and study the diverse group of arachnids more effectively. **

No, crabs do not belong to the arachnids. Arachnids are a class of joint-legged invertebrate animals that include spiders, scorpions, ticks, and mites.

While both arachnids and crabs are arthropods, they belong to different classes within the phylum. **

Several arachnids can occur on indoor plants, including spider mites, aphids, and thrips. Spider mites are a common pest that can infest indoor plants, causing damage to the leaves and overall health of the plant. Aphids and thrips are also known to infest indoor plants, feeding on the plant's sap and causing damage to the foliage. It's important to regularly inspect indoor plants for signs of these arachnid pests and take appropriate measures to control their populations. **

The main difference between spiders and other arachnids is that spiders have two body segments (cephalothorax and abdomen) and eight legs, while other arachnids, such as scorpions, ticks, and mites, have a fused body with no distinct segments and may have six or more legs. Additionally, spiders have silk-producing glands and use silk to build webs for catching prey, while other arachnids do not produce silk or use it in the same way. Finally, spiders have venomous fangs for subduing their prey, while other arachnids may have different methods of capturing and immobilizing their food. **
