Last week, researchers with the Nautilus Live expedition spotted this "googly-eyed stubby squid" nearly 3,000 feet underwater off the coast of California.
Even though it looks like an octopus or a squid, it's actually more closely related to the cuttlefish, like the one seen in the video below.
The same expedition also discovered a mysterious purple orb late last month. They're still not quite sure what it is.
Perhaps just as stunning is this new species of scorpionfish found in the deep-reef waters off the island of Curaçao in July.
And, they may not be pretty, but these two new species of bioluminescent deep-sea fish, also known as "barreleyes," are fascinating, too.
The strange discoveries will most likely keep on coming. In 2014, scientists said they identified almost 1,500 new species in the world's oceans, and that number continues to increase.
