More than 700 new species of sea creatures have been discovered in the waters of Antarctica. Scientists uncovered some weird and wonderful things - like this Ctenocidaris.
The harsh conditions in the area meant that scientists thought that few creatures could survive. But this Munna crustacean was among 1,000 species found living there.
Here's another tough name - this is a member of a family of creatures called Epimeriidae. It was previously unknown to scientists, despite its bright pink colour!
Check out this tiny and strange-looking creature - it's called a gastropod. It looks like a snail hiding in some cotton wool.
This is a young male isopod. The discovery of these creatures is really important because it can tell scientists about how sealife has changed in the Antarctic over the years.
Lots of the newly-discovered species were tiny, but this glass sponge was one of the team's larger finds. Scientists found 76 species of sponge - 37 of which they had never seen before.
The discoveries uncover differences between creatures in various parts of the sea. Take this Paraceradocus - those in the deep are white, but ones in shallow water are red!
