Morphological characteristics

The Kodiak brown bear is the largest subspecies of brown bears. It has a body length of 2 to 2.8 meters and a bodyweight of 650 kilograms or more. The average body weight exceeds that of polar bears. The largest individual has 800 kilograms. Their coats will change with the seasons. The summer coats are shorter and the color is darker. In winter, the coats are long, up to 10 cm, and the color is lighter than summer. The Kodiak brown bear has a long claw, but because it can’t be retracted into the claw sheath, the claw tip is relatively blunt. Even so, their claws are as strong as the destructive force.


The Kodiak brown bear is mainly distributed in Kodiak island, Alaska, and inhabits the forest area. They usually dig a nest in a relatively concealed environment, hide in the nest during the day, and go out in the morning. Kodiak island brown bears have their own territory, and they are very broad. Their territorial consciousness is very strong and they will run other bears that invade their territory.


Although the Kodiak brown bear is huge in size, with sharp teeth and extremely destructive claws, it looks very powerful and fierce, but they rarely eat meat but prefer to feed on plants, including various grasses. Tuber, grain, and fruit, plant foods account for 60% to 90% of their daily diet.
