Did you know that the ocean produces approximately half of the world's oxygen? Or that key medicines have come from ocean discoveries, like a painkiller found in a sea snail?
It's all true! And so is this fact: Scientists know more about space than Earth's ocean. Seriously, humans haven't seen 99.999% of the deep sea floor.
With this comic, we explore some of the cool things scientists do know about the ocean and what dwells inside of it.
