The name of the genus Thymallus first given to grayling (T. thymallus) described in the 1758 edition of Systema Naturae by Swedish zoologist Carl Linnaeus originates from the faint smell of the herb thyme, which emanates from the flesh.

The Arctic Grayling (Thymallus arcticus montanus) was originally distributed throughout the Madison River drainage below Firehole Falls and Gibbon Falls and the Gallatin River drainage. Introductions of brown and rainbow trout into the Madison River drainage caused the extirpation of the grayling from these rivers.
The grayling grows to a maximum recorded length of 60 cm (24 in) and a maximum recorded weight of 6.7 kg (15 lb). Of typical Thymallus appearance, the grayling proper is distinguished from the similar Arctic grayling (T. arcticus arcticus) by the presence of 5–8 dorsal and 3–4 anal spines, which are absent in the other species; T. thymallus also has a smaller number of soft rays in these fins.
The two populations are commonly called Montana Arctic grayling. [4] The Big Hole River Watershed Committee (BHWC) was formed in 1995 by several Big Hole ranchers and some factions of the conservation community who opposed an ESA listing for fluvial Arctic grayling.
