He works at its Museum of Comparative Zoology. Most crustaceans live in the water, Farrell points out. But some woodlice, also called rollie pollies, dwell on land. You probably know the two main types of myriapods: millipedes and centipedes. Myriapods live on land and most have lots of legs. These fangs are not chelicera. Centipedes instead eat with mandibles, as crustaceans and insects do. But they also have a pair of venomous, fang-like legs.
Millipedes, in contrast, are herbivores. So millipedes are much slower than centipedes. There are more species of insects on land than all other arthropods combined, says Kip Will. Bees fly, beetles crawl like tiny armored tanks and the Australian walking stick has camouflaged itself to look like a leaf mixed with a scorpion.
Another similarity is that they both have a fair share of poisonous species, such as scorpions. The Difference Between an Insect and an Arachnid The main difference between the two is that arachnids have eight legs four pairs of legs while insects have six three pairs of legs.

The nymph shed the old outer covering for its further growth. This process is called molting. Termites, ants, bees, wasps, and butterflies are examples of insects. Arachnids are wingless arthropods, consisting of a body with two segments: cephalothorax and abdomen. Archanis also have eight appendages and no antennae. Over , species of arachnids have been identified all over the world. Arachnids have simple eyes. They hatch eggs but, do not undergo metamorphosis. The typical body structure of an arachnid is shown in figure 2.
Arachnids are cold-blooded animals whose blood temperature depends on the temperature of the environment. Their blood is blue in color since it contains hemocyanin. They feed on the body fluids of the prey. Therefore, arachnids are carnivorous animals. Some arachnids make nests. Insects: Insects are small arthropods who possess six legs and one or two pairs of wings.
Arachnids: Arachnids are wingless arthropods, having a body with cephalothorax, abdomen, eight appendages, and no antennae. The main types of bugs Insects Insects have six legs and their body has three major segments: the head — includes eyes, mouthparts, and antennae the thorax — includes legs and sometimes wings the abdomen — includes gut, reproductive organs, and sometimes a stinger Examples of insects are dragonflies, flies, fleas, butterflies, moths, cicadas, beetles, bees, ants, and wasps.
