A lions mane jellyfish (Cyanea capillata). Every time a jellyfish pulses its bell, it draws water and entrained prey to its tentacles. The lions mane is one of the largest species of jellyfish. Clumping into giant formations, their tentacles--which may individually reach 100 feet in length--are lined with toxic stingers. That's longer than a 100-foot-long blue whale. The largest lions manes live in Arctic waters.

New creatures found in Antarctic deep-sea vents | Earth | EarthSky
An expedition to explore the creatures of deep-sea hydrothermal vents in the dark abyss of the Southern Ocean has revealed a “lost world,” straight out of a Jules Verne adventure. Scientists have found new species of crab, snail, sea star, barnacle, sea anemome, and even octopus. These animals thrive in total darkness, warmed by the heat of the vents, and mostly sustained by a food chain that begins with sulphur-oxidizing bacteria that thrive by the mineral-rich waters released from the…
