Historically, tigers ranged widely throughout Asia and ranged from Turkey into eastern Russia. They are now critically endangered, with just over 3,000 individuals left in the wild. The biggest threats to tigers are poaching by humans and disappearing habitat. Adult tigers need to consume 50-75 large prey animals per year to survive. Although some small-protected areas for tigers exist, tigers require a large home range with plenty of prey. Unfortunately, habitat fragmentation has detrimentally effected tiger populations because it has limited the spread and growth of prey. As a result, protective government programs would need to protect both the tigers as well as their prey species and habitats.

Based on the information in the passage, which of the following choices best describes the tiger species?
