the tiger is the largest cat species, reaching a total body length of up to 3.3 metres and weighing up to 306 kg. their most recognizable feature is a pattern of dark vertical stripes on reddish-orange fur with lighter underparts. they have exceptionally stout teeth, and their canines are the longest among living felids, with a crown height of up to 74.5 mm.they are territorial and generally solitary but social animals, often requiring large contiguous areas of habitat that support their prey requirements. this, coupled with the fact that they are indigenous to some of the more densely populated places on earth, has caused significant conflicts with humans. in zoos, tigers have live for 20 to 26 years, which also seems to be their longevity in the wild.
