The NOAA Office of Ocean Exploration and Research has a bunch of great photos and videos from a recent expedition to American Samoa. Photo above is the Cosmic Jellyfish.
In this video, you can see the perfectly relaxed arrangement of the two sets of tentacles; scientists think this is a position that allows for optimum feeding in the midwater environment at ~3,000 meters. Through remotely operated vehicle video observations such as this, we can learn much about the animals in the midwater and what they are up to when we can catch them in an undisturbed manner.
By the way, the White House is proposing a 17% cut to NOAA's budget.
