Answer:
INVERTEBRATES
Explanation:
Invertebrates are generally soft-bodied animals that lack a rigid internal skeleton for the attachment of muscles but often possess a hard outer skeleton (as in most mollusks, crustaceans, and insects) that serves, as well, for body protection.
Answer: In addition to not having a backbone, invertebrates have soft bodies because they don't have an internal skeleton (endoskeleton) for support.
