- Taxonomic Hierarchy: The term is used within the Linnaean classification system. For example: Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Gaviiformes, Family: Gaviidae, Genus: .
- Phylogenetic Studies: Used when discussing the evolutionary relationships between bird orders, e.g., "The phylogenetic position of Gaviiformes among other aquatic birds is a subject of research."
- Gaviiform (adjective): Of or relating to the order Gaviiformes.
- The gaviiform body plan is highly specialized for diving.
