### Instruction: Classify each of the following as either an insect or a worm: tequila worm, silk worm, glow worm, inchworms, earthworms, tapeworm, hookworm, liver fluke, threadworm
### Response: Both worms and insects are invertebrates in the animal kingdom, meaning they do not have backbones. Tapeworms, hookworms, liver flukes, and threadworms are examples of intestinal worms. Earthworms are also worms. Tequila worms, silkworms, glow worms, and inchworms are not worms. They are insects. Silkworms, for example, are the larva of silk moths.
