Lexile

When we think about the ocean, we may visualize sea turtles swimming around coral reefs, sea urchins anchored in tide pools and dolphins breaching the surface. Or even shrimp gathered around deepwater sulfur vents. But most of the ocean is just open water. Miles and miles of it from below the surface to thousands of feet down. This is the ocean midwater. It's the largest habitat on Earth!

Yet midwater habitat has not been well-studied. That's because it is difficult to explore. It's mostly cold, dark and under high pressure. Some of its most surprising secrets are animals without backbones. These are called invertebrates. Think of worms and jellies. They come in a variety of weird colors and shapes. Many of these midwater species have never been recorded by science. Scientists are challenged to figure out what they are.

Marine biologists use specialized equipment to find the open ocean's unique invertebrates. Remotely operated vehicles provide a view of the mysterious world of suspended life. The vehicles are essentially robots. They are controlled from ocean-going ships. Zoologists use the vehicles to catalogue and capture examples of organisms. Many never have been named before. Some of these organisms rewrite what we know about the intricate web of ocean biodiversity.

    I think it is very cool! i really like learning about the under water, because when i was very little i would watch finding nemo everyday! i think this is very intresting that we are finding out more about our world. I think we should keep looking for more
