Researchers aboard the E/V Nautilus (previously) celebrated the new year with an unlikely guest, a beautiful Halitrephes maasi jellyfish found at a depth of 4,000 feet underwater at the Revillagigedo Archipelago off Baja California, Mexico. The vibrantly hued jellyfish looks like an impressive burst of fireworks when lit, but would otherwise travel in almost completely visual obscurity.
