Crabs,Spiders,and Insects
All spiders are arachnids; they are closely related to scorpions, and distantly related to crabs and ants.
Ticks are not closely related to spiders. Ticks belong to the arachnid class, like spiders, but they are in a different order called Acari, while spiders are in the order Araneae. Both ticks and spiders have eight legs and belong to the same class, but they are not closely related in terms of their order.
No. Mites are arachnids, and so are related to spiders, but they are not actually spiders.
No, not always. Species from the Class 'Arachnida' have eight legs, however spiders (Order Araneae) is just one group of creatures in this order. Scorpions, mites, solifuges, are all examples of other eight-legged organisms that are related to spiders, but belong to different Orders.
Yes. Both spiders and scorpions are arachnids. Even though thay look different they are related to each other.
spiders, crabs, lobsters
Yes, they do.See the Related Link for more information about these spiders.
Actually, there are 5 groups of anthropods. The first is the Trilobites, which lived during the Permian-Triassic period and was wiped out by the extinction of that age. Chelicerates are spiders, mites, scorpions and related organisms. Myriapods are millipedes, centipedes, and other related organisms. Hexapods are insects and insect-like organisms that are included under anthropods. Finally, Crustaceans (except for woodlice) are aquatic organisms including lobsters, crabs and shrimp.
Wolf spiders, large but harmless organisms, live about 3 to 5 years. They like to come out at night.
