00:00:02.400 --> 00:00:07.440
We're at the moment going up a wall,
and you can see it's covered in sponges

00:00:07.440 --> 00:00:13.200
and some of them are particularly large.
Wow. Look at that side view.

00:00:15.280 --> 00:00:20.160
That huge sponge attached
to a seemingly small stalk.

00:00:23.200 --> 00:00:29.840
That's just beautiful.
Some great video.

00:00:31.280 --> 00:00:34.960
Look at those lasers.
So those lasers are 10 centimeters apart.

00:00:34.960 --> 00:00:38.160
So those are what we call laser scales.
They are how we tell what size things are

00:00:38.160 --> 00:00:39.840
on the seafloor.
My goodness.

00:00:40.720 --> 00:00:44.960
Well over a meter, if not
closer to a meter and a half.

00:00:47.120 --> 00:00:49.360
It's really such beautiful structure, too.

00:00:50.400 --> 00:00:54.880
It's created by a fusion of adjacent spicules.
So the soft sponges don't glue

00:00:54.880 --> 00:00:57.840
the spicules together,
whereas these hard sponges do.

00:01:01.600 --> 00:01:03.840
So you can actually see in
the live tissue this time,

00:01:03.840 --> 00:01:04.720
that matrix.

00:01:05.520 --> 00:01:09.360
As one of the pilots commented earlier, it
looks a little bit like fiberglass sheets.

00:01:10.560 --> 00:01:14.320
And that shows you really clearly the pores.
On each of those pores, there's specialized

00:01:14.320 --> 00:01:18.960
cells that have these flagella
that make water flow through them.

00:01:19.760 --> 00:01:23.520
And so the water goes through them and filters
out all the particulars that they want to eat

00:01:24.160 --> 00:01:27.520
and then the water without those
nutrients comes out the other side.

00:01:33.360 --> 00:01:39.840
That's really spectacular,
pilot, that's a really good shot.
