how do many invertebrates protect their soft body

Insects, crustaceans, and many other invertebrates have a hard outer case called an exoskeleton. This protects them against blows and predators, and keeps them from drying out. Slugs, leeches, and jellyfish have soft bodies and no exoskeleton. The pressure of fluids inside their bodies maintains their shape.

How do many invertebrates protect their soft body

Insects, crustaceans, and many other invertebrates have a hard outer case called an exoskeleton. This protects them against blows and predators, and keeps them from drying out. Slugs, leeches, and jellyfish have soft bodies and no exoskeleton. The pressure of fluids inside their bodies maintains their shape.

Do invertebrates have soft bodies?

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. The phylum Cnidaria includes the hydras, jellyfishes, and sea anemones.

What do invertebrates protect?

Invertebrates are animals that have no backbone or skeleton inside them. Instead, some have a tough outer shell for protection, while others have no hard parts in their bodies at all.

Why invertebrates are delicate and soft?

In addition to not having a backbone, invertebrates have soft bodies because they don't have an internal skeleton (endoskeleton) for support. Instead, many have structures on the outside (exoskeleton) that provide support and protection.
