What present day animal doe the saber tooth tiger resemble?

The saber-toothed tiger, or Smilodon, most closely resembles modern big cats, particularly the jaguar and lion, in terms of body structure and size. However, its most distinctive features are its long, curved canine teeth, which are not found in any present-day animal. While there are similarities in musculature and hunting behavior with today's big cats, the saber-toothed tiger's unique adaptations set it apart as a distinct species.
