Category:cy:Delphinids

Welsh terms for types or instances of (oceanic) dolphins, grampuses, killer whales/orcas, pilot whales, and other cetaceans in the family Delphinidae.

Note: river dolphins and porpoises are in other families.

NOTE: This is a set category. It should contain terms for delphinids, not merely terms related to delphinids. It may contain more general terms (e.g. types of delphinids) or more specific terms (e.g. names of specific delphinids), although there may be related categories specifically for these types of terms.
