How many legs do arachnids have?

Arachnids have 8 legs, 2 main body segments, no wings or antennae, and are not able to chew. In some species arachnids can grow extra appendages that can look like extra legs. They often get confused with insects, but insects only have 6 legs.

What do arachnids eat?

Most species of arachnids can only eat food in a liquid form and not in solids. They do so by squirting digestive chemicals into their prey and then sucking out the body juices. Arachnids typically eat insects and other invertebrates. Mites are the only arachnids who consume a wider variety of food like fungus, plants, dead animals, bacteria, and other invertebrates.

How are arachnids different from insects?

Arachnids have 8 legs while insects have 6. Arachnid bodies are divided into 2 parts, the cephalothorax and abdomen and insect bodies are divided into 3, the head, thorax, and abdomen. Arachnids do not have an antennae nor wings, while all insects have antennae and some also have wings. Insects belong to the Insect class and arachnids to the Arachnida class.

What is the largest group of arthropods?

The largest group of arthropods are insects, and they can be distinguished from other arthropods through specific characteristics. These characteristics include them having 3 body regions, 3 pairs of legs, as well as a pair of antennae. Most insects also have the ability to fly, which other arthropods lack.

How do arthropods grow?

The arthropods grow through the process of forming new segments near their tail. The growth of an arthropod is very similar to the growth of annelids. Arthropods like mollusks have a tough exoskeleton, but this exoskeleton does not grow along with the rest of the animal and they have to shed their exoskeleton periodically.

Why are arthropods important?

Arthropods are considered because they carry out a different number of roles and tasks. Arthropods can help with pest control or weed control, they also carry an important ecological role due to their large number of species and diversity. Arthropods also serve as food for other species within the food chain.

How do invertebrates protect their soft bodies?

Invertebrates can effectively protect their soft bodies through an outer hard casing that is referred to as the exoskeleton. Invertebrates like spiders, crustaceans, and insects have their exoskeletons made through sections of jointed legs. Others like mollusks like snails and clams have a hard shell in which they can hide when danger is present.

What is the difference between an invertebrate and a vertebrate?

The difference between an invertebrate and a vertebrate is that invertebrates have no backbones while vertebrates have a developed internal skeleton with cartilage and bones as well as a developed brain that is protected by a skull. Vertebrates also cannot make their food, while invertebrates make their food.
