The giant oarfish usually stays nearly 3,000 feet below the waves, but the world's longest bony fish was captured on camera by some lucky tourists.
Tourists actually saw two of the rare creatures off the coast of Mexico in the shallow waters of the Sea of Cortes. The baffling creatures can grow to be more than 50 feet long, and are thought to be the source of legends about sea serpents. (Could you blame anyone who came across an oarfish for thinking that they had encountered a monster?)
The oarfish these tourists saw were about 15 feet long.
