List off 5 other animals with an exoskeleton (not from this phylum).

Here are five animals with exoskeletons that are *not* insects (insects belong to the phylum Arthropoda, and the prompt specifies not from that phylum):1. **Barnacles (Crustacea):** While related to insects (both are arthropods), barnacles are crustaceans and have a calcareous exoskeleton. They are sessile, meaning they attach to surfaces like rocks and ships.2. **Crabs (Crustacea):** Another crustacean, crabs have a chitinous exoskeleton that they molt as they grow.3. **Snails (Mollusca):** Snails have a hard, calcium carbonate shell that serves as an exoskeleton, protecting their soft bodies.4. **Chitons (Mollusca):** These marine mollusks have a shell composed of eight overlapping plates, offering protection and flexibility.5. **Brachiopods (Brachiopoda):** These marine animals resemble clams but are in a different phylum. They have a two-part shell (valves) made of calcium carbonate or calcium phosphate.
