There are a lot of very freaky looking animals out there that are still being discovered to this day. One such animal was recently discovered just above the Mariana trench: A “Jack-o-lantern” jellyfish whose head lights up like a Halloween pumpkin.

This strange creature was first spotted last month in the Pacific Ocean at a depth of almost 4 kilometers.

“Scientists believe this animal belongs to the genus Crossota, a group of jellies that does not have a sessile polyp stage; all phases of their lives are ocean drifters,” Scientific American informs us. “They also believe this animal is an ambush predator – note the posture it had assumed in the first half of the video: its bell motionless with its tentacles outstretched like the struts of a spider’s web, waiting for something to bumble into them. The red canals, they suggest, appear to connect the bright yellow objects, which may be gonads.”
