Sibirische Tiger (Panthera tigris altaica) (XI)

Sibirische Tiger (Panthera tigris altaica) (XI)

The ground colour of Siberian tigers' pelage is often very pale, especially in winter coat. However, variations within populations may be considerable. Individual variation is also found in form, length, and partly in colour, of the dark stripes, which have been described as being dark brown rather than black.[21]

The fur of the Siberian tiger is moderately thick, coarse and sparse compared to that of other felids living in the former Soviet Union. Compared to the now-extinct westernmost populations, the Far Eastern Siberian tiger's summer and winter coats contrast sharply with other subspecies. Generally, the coat of western populations was brighter and more uniform than that of the Far Eastern populations. The summer coat is coarse, while the winter coat is denser, longer, softer, and silkier. The winter fur often appears quite shaggy on the trunk, and is markedly longer on the head, almost covering the ears. Apart from that, Siberian and Caspian tigers had the thickest fur amongst tigers, given their occurrence in the more temperate parts of Eurasia.[9][8]

The whiskers and hair on the back of the head and the top of the neck are also greatly elongated. The background color of the winter coat is generally less bright and rusty compared to that of the summer coat. Due to the winter fur's greater length, the stripes appear broader with less defined outlines. The summer fur on the back is 15–17 mm (0.59–0.67 in) long, 30–50 mm (1.2–2.0 in) along the top of the neck, 25–35 mm (0.98–1.38 in) on the abdomen, and 14–16 mm (0.55–0.63 in) on the tail. The winter fur on the back is 40–50 mm (1.6–2.0 in), 70–110 mm (2.8–4.3 in) on the top of the neck, 70–95 mm (2.8–3.7 in) on the throat, 60–100 mm (2.4–3.9 in) on the chest and 65–105 mm (2.6–4.1 in) on the abdomen. The whiskers are 90–115 mm (3.5–4.5 in).
