Watch flower-hat jellies float around like fluorescent creatures from Avatar

The Tennessee Aquarium recently welcomed some new arrivals: fluorescent flower-hat jellies.

Flower-hat Jellyfish (Olindias formosa) are the newest addition to the Tennessee Aquarium's Jellies: Living Art gallery. This bizarre, spectacular species is noteworthy for being semi-benthic (bottom-dwelling) rather than drifting or free-swimming and for their colorful tentacles, which project from every side of their bells. This species has never been exhibited at the Aquarium before.

Here's some nice footage of their tentacles in closeup:
