Yes, they all belong to the phylum Arthropoda.
Scorpions are not related to crabs. Scorpions are part of the arachnid family while crabs are a part of the crustacean family.
They are both part of the same species group
No, its an Arachnid - a spider, it has 8 legs not 6It is not it is part of the spider family
Insects have an exoskeleton, a three-part body (head, thorax, and abdomen), three pairs of jointed legs, compound eyes, and two antennae. Spiders have eight legs, soft bodies. Spiders belong to the class of arachnids which also includes scorpions, ticks and mites. None of these are actually classed as insects. Unlike insects they have eight legs, eight eyes in most cases, no wings,and only two, not three parts to their bodies.
They do not have backbones. Scorpions are part of the invertebrate family, which include arthropods, mulloscs, Annelids and poriferans. Invertebrate means that they don't have backbones. Some arthropods have exoskeletons, but none in all of the invertebrates have an internal skeleton.
No, they are part of the Arachnid family. Many people think of spiders as insects, but actually they are classified in a separate category. Spiders are part of a group called arachnids, which also includes mites, ticks, and scorpions. Arachnids share many features with their arthropod cousins, but they differ in that they do not have antennae. Also, spiders have eight legs (insects have six), and their bodies are segmented into two parts (insects' bodies have three parts).
yes they are
Their legs, and the muscles to use these, contained in the thorax (second part in insects, first in spiders and crustaceans).
Arachnids are spiders, scorpions, ticks, and mites. Insects are organisms like grasshoppers and bees. Insects, unlike arachnids, can often fly and usually have three pairs of legs. Arachnids have many legs. The spider has eight legs.
Arachnids, by definition are eight legged invertebrate animals. While they both are in the arthropod classification, they still have differences. Insects have a three part body, two eyes, three pairs of jointed legs, and two antennae. Spiders do not have those, so the answer to your question is no.
Scorpions are not related to crabs. Scorpions are part of the arachnid family while crabs are a part of the crustacean family.
Spiders belong to the class Arachnida, which includes other arachnids such as scorpions, ticks, and mites. They are distinct from insects, which belong to the class Insecta.
Animals are divided into two groups, vertebrates and invertebrates. Vertebrates are animals with a backbone and invertebrates are animals without a backbone. In the invertebrates group there are mollusks, Insects, crustaceans and arachnids. Spiders are part of the arachnid group along with scorpions.
They are both part of the same species group
Yes, entomologists study spiders as part of their research on insects and other arthropods.
Cephalothorax means 'head chest', and it is exactly what it sounds like. Spiders have one, being the frontmost part of their bodies. Insects have a separate head and thorax, but spiders have their eyes and jaws (head) on the same part as their legs (thorax in insects).
The arthropods are far from extinct. They are one of the largest groups of animals, and include about anything with an exoskeleton. Insects, spiders, crabs, lobsters, crayfish, beetles (which are insects), scorpions, and so on.
