Tigers have striped fur, usually black stripes on orange with a white underbelly. Even rarer, stripeless tigers have been recorded. Males are larger than females. Like most cats, their night-time vision is very good.
Tigers have retractible claws.
Tigers have the largest canine teeth of any land-based carnivores. Sometimes tigers gather to share a large kill. Tigers mark out their territory, like most cats, by spraying their urine together with a glandular secretion, by leaving fecal droppings, or by scratching marks into trees with their claws. Tigers need a territory of about 10-30 or more square miles to provide enough prey to support them. The size of the territory depends on the amount of prey available in the area.
