3 minutes

(Describer) Under a round logo of a wave, title: Ocean Today.

(female narrator) The deep ocean-- a place so different, filled with strange life forms. But what's down there? How much do we know about it? As it turns out, not very much. Ninety-five percent of the ocean remains unexplored, most of which is considered "the deep ocean."

(Describer) An animated view goes underwater. It dives.

But what exactly is the deep ocean? The first 200 meters of the ocean are the open ocean. Much of the marine life we know of lives here, where there is light. Below 200 meters, where there is little light left, you enter the "twilight zone."

(Describer) ...between 200 and 1000 meters.

Once you pass 1,000 meters, the water is completely devoid of light and you have reached the deep ocean. Down here, temperatures plummet to 39 degrees Fahrenheit and constantly stay near freezing. The pressures at these depths range from about 40 to over 110 times the pressure of Earth's atmosphere. But how could anything thrive in these conditions?

(Describer) A couple creatures are shown.

It was originally thought that life cannot survive without light. We now know that despite this lack of light, many creatures can live in this extreme place, such as microorganisms in hydrothermal vents...

(Describer) White plumes rise from holes.

deep-sea corals, fish, and many other bizarre creatures.

(Describer) One is round, purple and spiky, then unfolds itself.

Exploring the deep ocean is challenging because of the harsh conditions, but marine scientists are on a mission to document new species in this unusual place.
