This is What's Trending Today:
There are still lots of undiscovered areas around the globe – but most are below the surface of the ocean.
Recently, the U.S. National Oceanic and Atmospheric Administration, or NOAA, discovered something new on the ocean floor.
And everyone is calling it "cute" and "adorable".
And people on social media love it.
Scientists say it might be a new species of octopus. It is similar to some octopi that live in shallow water, but this one was found more than 4,000 meters below the surface.
Before this new discovery, the only octopi found in water this deep were very different.
Some people want to name it Casper after the famous ghost of cartoons and movies.
NOAA posted a video to YouTube of the octopus sitting on the ocean floor and wiggling its arms. It has more than 200,000 views since March 3.
The science writer Melissa Dahl called the octopus "adorable."
"Aww" is the sound people make when they are looking at something cute, like a puppy or baby. "Awe" is a word used to describe something unique and impressive.
But the octopus is not only "cute" and "adorable." It looks to be an important scientific discovery. The scientists at NOAA say the octopus may be part of a new species.
And the funny thing is, NOAA was not looking for new sea creatures. It is investigating the way some islands near the U.S. state of Hawaii formed many years ago.
To do this, the scientists aboard a ship drop some remote-controlled submarines into the ocean. They go down to the floor, more than 4,000 meters deep, and collect rock samples.
As soon as the investigators saw this octopus, they said it was "beautiful ... different than the two we got on video last year." They also said it was definitely not in the "HURL guide," which is a directory of undersea creatures in the Pacific Ocean.
NOAA released images and video of this new octopus in early March and people on social media sites started talking about it over the weekend.
And that's What's Trending Today.
