In this video, shot by staff photographer Todd Stailey, you'll go behind the scenes at the Tennessee Aquarium with aquarist Ben Stenger to feed the prehistoric-looking Arapaima (Arapaima gigas).
This species is the largest fish that is found strictly in fresh water. The arapaima is very unique among fish— it can breathe air! They have a very primitive lung. They can take up oxygen through their gills also but they typically live in oxygen-poor waterways and supplement with air breathing. The arapaima is a fierce and stealthy predator. They feed on the surface of the water and will even jump out of the water and grab birds, lizards and small primates from low-hanging branches. Tennessee Aquarium visitors can see arapaima in the new River Giants exhibit.
