Salmonidae
Salmonidae
Salmonidae (pronounced sal-MON-i-dee) is a family of ray-finned fish, the only living family currently placed in the order Salmoniformes. It includes salmon, trout, chars, freshwater whitefishes, and graylings, which collectively are known as the salmonids.
Etymology
The term "Salmonidae" is derived from the Latin word "salmo," which itself was likely borrowed from the Celtic word for "leaper," reflecting the fish's well-known jumping ability.
Description
The Salmonidae are native to tributaries of the North Atlantic (genus Salmo) and Pacific Ocean (genus Oncorhynchus). Many species of this family are anadromous, meaning they are born in fresh water, migrate to the ocean, then return to fresh water to reproduce. However, there are also many species that live their entire life in fresh water.
Species
The family Salmonidae includes three subfamilies and around 66 species, including:
- Salmon (Salmo)
- Trout (Salvelinus, Oncorhynchus)
- Char (Salvelinus)
- Freshwater whitefish (Coregonus)
- Grayling (Thymallus)
