Arctic Grayling: The Arctic grayling is an elegantly formed cousin of the trout. With its sail-like dorsal fin dotted with large iridescent red or purple spots, the grayling is one of the most unusual and beautiful fish of Alaska. Grayling are generally dark on the back and have iridescent gray sides. They have varying numbers of black spots scattered along the anterior portion of both sides. The adipose, caudal (tail), pectoral, and anal fins are dusky brown and the pelvic fins are often marked with pink to orange stripes.

Dolly Varden: Young Dolly Varden have about eight to ten wide, dark parr marks or oval blotches which contrast with the mottled olive-brown color of their body. The sea-run fish are silvery with an olive-green to brown color on the dorsal surface and numerous red to orange spots on their sides. The mature males become brilliant red on the lower body surface, and the lower fins become reddish-black with white along the leading edges. Mature females are similar but are less brightly colored. Males develop an extended lower jaw which hooks upward, fitting into a groove which is formed in the upper jaw. A hook also forms in the females but is considerably less developed.

Dolly Varden belong to a group of fish called char. The light spots on their sides distinguish them from most trout and salmon which are usually black spotted or speckled.
