Why is a hissing cockroach an invertebrate?
A hissing cockroach is an invertebrate because it lacks a backbone or vertebral column. Invertebrates are animals that do not have a backbone, and they make up the vast majority of animal species on Earth. Insects, spiders, worms, and mollusks are all examples of invertebrates.
