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.
