Have you ever wondered what's going on way down at the bottom of the ocean?

Perhaps you are a scuba diver and already know. I've been snorkeling and it's a lot of fun and can be very beautiful but it's really close to the surface.

So, I was really excited to see this short video about the underwater world.

I learned a lot myself so I hope you will not only learn some new English words, but also learn some cool facts too.

Transcript of David Gallo's talk:

We're going to go on a dive to the deep sea, and anyone that's had that lovely opportunity knows that for about two and half hours on the way down, it's a perfectly positively pitch-black world.

And we used to see the most mysterious animals out the window that you couldn't describe: these blinking lights—a world of bioluminescence, like fireflies.

Dr. Edith Widder—she's now at the Ocean Research and Conservation Association—was able to come up with a camera that could capture some of these incredible animals, and that's what you're seeing here on the screen.

That's all bioluminescence.

So, like I said: just like fireflies.

There's a flying turkey under a tree. (Laughter)
