| Hermaphrodite | An animal that produces both sperm and eggs. |
| Larva | Fertilized sponge eggs develop into young called this. Also the second stage of complete metamorphosis. |

| Herbivore | Animals that only eat producers. |
| Carnivores | Animals that only eat other consumers. |
| Omnivores | Animals that eat both producers AND other consumers. |
| Bilateral Symmetry | Animals that can be divided into right and left halves have this type of symmmetry. |
| Radial Symmetry | Animals that have body parts arrranged in a circle around a center point have this type of symmetry. |
| Asymmetry | Animals that have no apparent symmetry such as sponges and corals have this type. |
| Free-living organism | This type of animal does NOT depend on another single organism for food or a place to live. |
| Parasites | Animals that rely on one specific organism for food and a place to live. |
| Anus | Opening at the end of the digestive tract. |
| Flatworms | This phylum includes tapeworms, flukes, and planarians. |
