This bulbous red fish with spiky scales and foot-like fins is a species of Sea Toad (Chaunacops coloratus)that has never been seen alive - until now! Researchers are thrilled to have spotted this rare deep-sea fish in its natural habitat. In addition to documenting it "walking" along the ocean floor and fishing with their built-in lures they've documented that it actually changes color from blue to red as it ages.
