Detailed Explanation on Instagram: "Arapaima eat incredibly fast, using a “vacuum” or “gulper” feeding strategy that can inhale prey in a fraction of a second. Because they live in murky Amazonian waters where visibility is low, they don’t rely on chasing down prey over long distances, instead using explosive, short-range attacks."

To catch prey, cheetahs have to get every part of the hunt right. #CheetahsUpClose
