What is the difference between bears and tigers?

Answer 1

Bears have a large body with stocky legs, a long snout, shaggy hair, plantigrade paws with nonretractile claws, and a short tail. Bears are classified as caniforms, or doglike carnivorans. Some polar bears and brown bears weigh 750 Kg.

Tigers have excepionally stout teeth, and their canines are the longest among felids;

It is the largest cat species, reaching a total body lenght of up to 3.3 metres and weighing 300 Kg. Tigers have muscular bodies with particularly powerful forelimbs and large heads. The tiger is the most variable in size of all big cats, even more than the leopards and lions. The accepted record weight, per the Guiness Book, for a wild tiger was 390 Kg, for a Bengal Tiger, shot in 1967, though its weight may have been boasted by the fact it had eaten a water buffalo the previous night.
