Oceanic | Marine Animals
The oceanic biome is by far the largest biome on Earth with 70% of the Earth being covered by the ocean. It is estimated that 1 million species live in the ocean, with most of those, about 95%, being invertebrates, like jellyfish and shrimp. There are also a few mammals, like Dolphins and Sea Lions, that live in the ocean with the largest being the Blue Whale. Although the ocean is one continuous body water, there are five different oceans: the Pacific, Atlantic, Indian, Antarctic, and Arctic. Being such a vast biome, it is believed that only about 5% of the ocean has been explored—leaving many more species of plants and animals undiscovered.
