On a Shedd Aquarium trip to Baja, Mexico last month two rare 15-foot oarfish (Regalecus glesne) were filmed swimming in the shallows. Oarfish are deepwater fish and rarely venture close to shore.
Sadly the two Oarfish encountered repeatedly beached themselves, and expired shortly after the video was filmed.
Here is a video of a thriving Oarfish at 1500 feet deep from 2013, filmed by GulfSERPENT project.
