In October 2013, Walter sustained a gunshot injury in Tofino, British Columbia, which permanently blinded him. Several people reported the injury after they noticed the wild otter acting tired and in need of medical attention, according to the Huffington Post.
The video was taken a few months after his arrival at the rescue center - he'd already received treatment for a fractured flipper and dental injuries. As you can see, he's a happy camper as he uses his tiny paws to quickly handle the delicious clams.
"Walter is not unique in using touch to sense where the food is," the rescue center wrote in the video's caption. "Sea otters feel for food along the ocean bottom with their sensitive front paws."
The rescue center originally planned to return Walter to the wild, but his blindness has made it difficult for him to live without the care of humans.
