| endoskeleton | a skeleton on the inside of a creature's body, typically composed of bone or cartilage |
| veins | blood vessels that carry blood towards the heart |
| optic lobes | the regions of the brain that receive signals from the receptors in the eyes |
| internal fertilization | the process by which the male places sperm inside the female's body where eggs are fertilized |
| olfactory lobes | the regions of the brain that receive signals from the receptors in the nose |
| cerebellum | the lobe that controls involuntary actions and refines muscle movement |
| external fertilization | the process by which the female lays eggs and the male fertilizes them once they are outside of the female |
| oviparous development | development that occurs in an egg which is hatched outside the female's body |
| arteries | blood vessels that carry the blood away from the heart |
| closed circulatory system | a circulatory system in which the oxygen-carrying blood cells never leave the blood vessels |
| bone marrow | the soft tissue inside the bone that produces blood cells |
| vertebrae | segments of bone or other hard substance that are arranged into a backbone |
| notochord | a rod of flexible material that runs the length of a creature's body, providing the majority of its support |
| appendicular skeleton | the portion of the skeleton that attaches to the axial skeleton and has the limbs attached to it |
| Atrium | a heart chamber that receives blood |
| ectothermic | lacking an internal mechanism for regulating body heat |
| cerebrum | the lobes of the brain that integrate sensory information and coordinate the creature's response to that information |
| medulla oblongata | the lobes that coordinate vital functions, such as those of the circulatory and respiratory systems, and transport signals from the brain to the spinal chord |
| bile | a mixture of salts and phospholipids that aids in the breakdown of fat |
| anadromous | a life cycle in which creatures are hatched in fresh water, migrate to salt water as adults, and then go back to fresh water in order to reproduce |
| ventricle | a heart chamber from which blood is pumped out |
| hibernation | a state of extremely low metabolism |
| ovoviviparous development | development occurs in an egg which is hatched inside the female body |
| capillaries | tiny, thin-walled blood vessels that allow the exchange of gasses and nutrients between the blood and cells |
| axial skeleton | the portion of the skeleton that supports and protects the head, neck and trunk |
| viviparous development | development that occurs inside the female, allowing the offspring to gain nutrients and vital substances from the mother through a placenta |
