Yellowstone cutthroat trout thrive in cold, clear, and well-oxygenated waters
They are commonly found in mountain streams, rivers, and high-altitude lakes
This trout prefers areas with gravelly bottoms for spawning, often near undercut banks or deep pools
Their diet mainly consists of aquatic insects, small fish, and crustaceans
Spawning occurs in the spring, with trout moving to shallow, gravelly stream beds
During spawning, males develop more vivid coloration, particularly around their gill plates
Post-spawning, they return to deeper waters where they focus on feeding and growth
Juveniles stay in sheltered areas until they mature, avoiding larger predators
