First contact, Amazon River Dolphin, Brazil: Photo by Kevin Schafer – @schaferpho @ナショナルジオグラフィック #onassignment – There were many images from my work with Amazon River Dolphins (Botos in Portuguese) that never made it into the final NatGeo story. This is one of them, an underwater close-up portrait taken during my first encounter with these extraordinary animals. It is a pretty straightforward picture but reveals a great deal about the lives and adaptations of these unusual animals. One of the first things you notice is their small eyes, almost useless in these murky waters where visibility is measured in inches, not feet. Their large, bulging foreheads, meanwhile, serve as “substitute" eyes, containing the sonar system that allows them to navigate the flooded forest and find their prey. Meanwhile, their impossibly long snouts - exaggerated somewhat here by my wide angle lens - are lined with teeth, an adaptation to clamp down on fish they can’t truly see. Finally, if you look closer, you will see hairs growing along the top of their snouts; these apparently help sense motion of objects around them, an additional tool for helping Botos find their food. Botos are still abundant in the vast Amazon-Orinoco River systems of South America, but this is no cause for complacency; they are too often killed and used for bait by fishermen, despite laws meant to protect them. Several other river dolphin species around the world are already extinct - or on the brink. This is one species we can save, if we have the will to do so. #boto #amazondolphin #floodedforest
