What called some invertebrates have outer body that protects their soft and delicate bodies?

The outer body that protects the soft and delicate bodies of some invertebrates is called an exoskeleton.

Here's some more information:

* Exoskeletons are hard, protective coverings found on the outside of the body. They provide support, protection from predators, and help with movement.

* Examples of invertebrates with exoskeletons:

* Insects: Beetles, butterflies, ants, etc.

* Crustaceans: Crabs, lobsters, shrimp, etc.

* Arachnids: Spiders, scorpions, ticks, etc.

* Composition: Exoskeletons can be made of various materials like chitin (a tough, fibrous substance), calcium carbonate, or a combination of both.

* Growth: Animals with exoskeletons must shed their exoskeletons (molt) as they grow larger.
