Marine biology is the scientific study of organisms in the ocean or other marine bodies of water. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy. Marine biology differs from marine ecology as marine ecology is focused on how organisms interact with each other and the environment, while biology is the study of the organisms themselves.
A large proportion of all life on Earth lives in the ocean. Exactly how large the proportion is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world covering approximately 71% of the Earth's surface. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10,000 meters or more beneath the surface of the ocean. Specific habitats include coral reefs, kelp forests, seagrass meadows, the surrounds of seamounts and thermal vents, tidepools, muddy, sandy and rocky bottoms, and the open ocean (pelagic) zone, where solid objects are rare and the surface of the water is the only visible boundary. The organisms studied range from microscopic phytoplankton and zooplankton to huge cetaceans (whales) 30 meters (98 feet) in length.
I hear a voice say "Don't be so blind"
It's telling me all these things
That you would probably hide
Am I your one and only desire?
Am I the reason you breathe
Or am I the reason you cry?
Always, always, always
Always, always, always
I just can't live without you
I love you, I hate you
I can't get around you
I breathe you, I taste you
I can't live without you
I just can't take anymore
This life of solitude
I guess that I'm out the door
And now I'm done with you
I feel like you don't want me around
I guess I'll pack all my things
I guess I'll see you around
It's all been bottled up until now
As I walk out your door
All I can hear is the sound of
Always, always, always
Always, always, always
I just can't live without you
I love you, I hate you
I can't get around you
I breathe you, I taste you
I can't live without you
I just can't take anymore
This life of solitude
I guess that I'm out the door
And now I'm done with you
I love you, I hate you
I can't live without you
I left my head around your heart
Why would you tear my world apart?
Always, always, always, always
I see the blood all over your hands
Does it make you feel more like a man?
Was it all just a part of your plan?
The pistol's shakin' in my hands
And all I hear is the sound
I love you, I hate you
I can't live without you
I breathe you, I taste you
I can't live without you
I just can't take anymore
This life of solitude
I guess that I'm out the door
And now I'm done with you
I love you, I hate you
I can't live without you
I love you, I hate you
I can't live without you
I just can't take anymore
This life of solitude
I pick myself off the floor
And now I'm done with you
Always, always, always
