The Feline Family
Tigers, lions, jaguars and leopards are the largest felines. While the tiger is the largest big cat, lions are the second largest, followed by jaguars and leopards. In short, the jaguar is the third largest big cat in the world. Unlike other felines, those in genus Panthera have the ability to roar. So Jaguars can roar, though their roars are like a repetitive cough.
