The ocean biomes have the biggest animal habitats on Earth. Since the ocean is the largest biome on Earth, scientists haven't found a lot of information about ocean animals compared to land animals. Our technology isn't that advanced to go to the deepest and darkest parts of the ocean so we may not know what kind of animals are there. There are many unique and beautiful ocean creatures that live in these oceans and you can see some in the slideshow above or in the youtube video below.
