cheetah is the only big cat that can’t roar? Instead, they communicate with chirps, purrs, growls, and even meows yet they remain the fastest land animal on Earth, reaching up to 120 km/h in short bursts. Grace, speed, and elegance… all in one masterpiece of nature. . . . . . . #cheetah #tanzaniainsideandsafari #wildlifephotography | Tanzania Inside and Safari
