| Annelida | A phylum of worm-like animals with metamerism. |
| Anthropoids | A clade consisting of monkeys, apes, and humans. |
| Anura | Frogs. |
| Bilateral Symmetry | A type of symmetry in which there is only one plane of symmetry that creates two mirror-image sides. |
| Budding | A form of asexual reproduction that occurs through the growth of a new organism as a branch on an adult organism that breaks off and becomes independent; found in plants, sponges, cnidarians, and some other invertebrates. |
| Cephalothorax | A fused head and thorax. |
| Chitin | A tough nitrogen-containing polysaccharide found in the cuticles of arthropods and the cell walls of fungi. |
| Chordata | A phylum of animals distinguished by their possession of a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail at some point during their development. |
| Cnidaria | A phylum of animals that are diploblastic and have radial symmetry and stinging cells. |
| Dioecious | Having separate male and female sexes. |
| Down Feather | Feather specialized for insulation. |
| Fragmentation | A form of asexual reproduction in which a portion of the body of an organism breaks off and develops into a living independent organism; found in plants, sponges, and some other invertebrates. |
| Germ Layer | A collection of cells formed during embryogenesis that will give rise to future body tissues. |
| Mammal | One of the groups of endothermic vertebrates that possess hair and mammary glands. |
| Mammary Gland | In female mammals, a gland that produces milk for newborns. |
| Mantle | A specialized epidermis that encloses all visceral organs and secretes shells in mollusks. |

| Metamerism | Having a series of body structures that are similar internally and externally, such as segments. |
| Nacre | A calcareous secretion produced by bivalve mollusks to line the inner side of shells as well as to coat foreign particulate matter. |
| Notochord | A flexible, rod-shaped structure that is found in the embryonic stage of all chordates and in the adult stage of some chordates. |
| Polyp | The stalk-like, sessile life form of a cnidarian with mouth and tentacles facing upward, usually sessile but may be able to glide along a surface. |
| Porifera | A phylum of animals with no true tissues, but a porous body with a rudimentary endoskeleton. |
| Primates | Includes lemurs, tarsiers, monkeys, apes, and humans. |
| Spicule | A short sliver or spike-like structure; in sponges, they are formed of silicon dioxide, calcium carbonate, or protein, and are found in the mesohyl. |
| Swim Bladder | In fishes, a gas-filled organ that helps to control the buoyancy of the fish. |
| Water Vascular System | A system in echinoderms in which water is the circulatory fluid. |
