Giant Phantom Jellyfish

Here's a rare sighting last month of a giant phantom jellyfish, which has four ribbon-like arms that grow more than 33 feet long.

According to the Monterey Bay Aquarium: 
"The giant phantom jelly was first collected in 1899. Since then, scientists have only encountered this animal about 100 times. It appears to have a worldwide distribution and has been recorded in all ocean basins except for the Arctic. The challenges of accessing its deep-water habitat contribute to the relative scarcity of sightings for such a large and broadly distributed species."
