Tigers are the largest members of the cat family (Felidae) and one of the most charismatic endangered species on the planet.
Over the last century, tiger numbers have fallen by about 95 percent and tigers now survive in 40 percent less of the area they occupied just a decade ago, according to the World Wildlife Fund (WWF).
Tigers have the species name Panthera tigris. There are nine subspecies of tigers, three of which are extinct.
A meeting set to begin in Russia on Sunday (Nov. 21) will examine some of the issues facing tigers in the wild and efforts to better conserve the six surviving tiger subspecies. Here we look at what sets each of these species apart.
