Happy #WorldRiversDay! The catfish is in a class of its own, with species that can be found in rivers across the Americas, Africa, Asia, and Europe. Some species we have seen on #rivermonsters and #darkwaters include the Wels catfish, Mekong catfish, and Goonch catfish (just to name a few). #videooftheday . . . . . . . . . #riverfish #freshwaterfish #catfish #catfishspecies #freshwater #rivermonster #jeremywade #animalplanet #photooftheday
