| Anadromous | An animal that lives as an adult in the ocean but returns to freshwater to spawn. |
| Apomorphic | An evolutionarily advanced or derived character. |
| Bathyal | The benthic environment in the ocean that exists between 1,000 and 4,000 meters, also referred to as the continental rise. |
| Bathypelagic | The pelagic zone of oceanic waters between 1,000 and 4,000 meters |
| Benthic | The seafloor |
| Catadromous | An animal that lives as an adult in freshwater but migrates to the ocean to spawn. |
