Why are worms not insects?

Answer 1

A bat is a mammal--it has fur, lactates and is warm-blooded. Mammals are vertebrates. Vertebrates have a dorsal nerve cord protected by bony or cartilaginous vertebrae. Arthropods are invertebrates--they do not have vertebrae. They are a specific kind of invertebrate with a jointed exoskeleton.

Answer 2

Although they are both invertebrates, the phylum of arthropods includes insects, crustaceans, arachniads-Spiders, millipedes and centipedes. Arthropods have these 5 main characteristics which do not all apply to the earthworm: hard outer covering- exoskeleton, specialized mouth parts, compound eyes, jointed legs, and segmented body.

Segmented worms- earthworms, leeches, and marine worms, belong to the phylum Annelida. Some characteristics that tell this phylum from the others are, cylindrical, long body made up of many segments, no appendages, no obvious "head"end, and no antennae.

Answer 3

Answer 4

The millipede has a chitinous exoskeleton, which makes it an arthropod rather than a worm.
