PHOTOS: "Alien" Jellyfish Found in Arctic Deep

This red-and-purple Crossota millsae, collected deep in the Arctic Ocean in 2005, is also found off of California and Hawaii, a scientist said in December 2009.

Biologists are realizing that jellyfish are more common predators in the oceans than thought, Monterey Peninsula College's Raskoff said by email.

"They are a very underappreciated and understudied group that have big roles to play in the food webs of the deep sea."
