Deep Sea Fireworks

A Hercules ROV operated by a team from E/V Nautilus off the coast of Baja California were trying to catch a crab when a beautiful distraction came into view. This is Halitrephes maasi, a deep-sea jellyfish that resembles a fireworks display in the dark waters. 

The frilled tentacles of the Halitrephes maasi jelly came into view at 1225m in the Revillagigedo Archipelago off Baja California, Mexico. Radial canals that move nutrients through the jelly's bell form a starburst pattern that reflects the lights of ROV Hercules with bright splashes of yellow and pink--but without our lights this gelatinous beauty drifts unseen in the dark.

This video, posted just a week ago, pretty much makes all the information for Wikipedia's entry on the species. (via Madam Jujujive)
