NOAA Office of Ocean Exploration and Research, 2015 Hohonu Moana

Seen at 1,500 meters (4,920 feet) depth during the 2015 Hohonu Moana: Exploring Deep Waters off Hawaiʻi expedition, this (rather large!) sea anemone measured nearly 30 centimeters (1 foot) across.

As an added bonus for #WormWednesday, it was covered in scale worms.
