Florida panthers are spotted at birth and typically have blue eyes. As the panther grows, the spots fade and the coat becomes completely tan, while the eyes typically take on a yellow hue. The panther’s underbelly is a creamy white, and it has black tips on the tail and ears. Florida panthers lack the ability to roar, and instead make distinct sounds that include whistles, chirps, growls, hisses, and purrs. Florida panthers are midsized for the species, being smaller than cougars from Northern and Southern climes, but larger than cougars from the neotropics.
Adult female Florida panthers weigh 29–45. 5 kg (64–100 lb), whereas the larger males weigh 45. 5–72 kg (100–159 lb). Total length is from 1. 8 to 2. 2 m (5. 9 to 7. 2 ft) and shoulder height is 60–70 cm (24–28 in). Male panthers, on average, are 9. 4% longer and 33. 2% heavier than females because males grow at a faster rate than females and for a longer time.
