We're at 1,150 feet and 250 feet off the bottom.

00:08.775 --> 00:13.980 align:left position:32.5%,start line:83% size:57.5%
Unchanged for
eons the dark alien deaths and miles of

00:14.080 --> 00:23.757 align:left position:85%,start line:83% size:5%
uncharted territory of the deep sea
tease the curious with their unexplored secrets.

00:23.857 --> 00:30.764 align:left position:77.5%,start line:83% size:12.5%
Every time you go down in the submersible
there's always something that's a surprise.

00:30.864 --> 00:34.768 align:left position:82.5%,start line:89% size:7.5%
Every submersible dive is a discovery.

00:34.868 --> 00:40.840 align:left position:75%,start line:83% size:15%
My favorite thing is seeing some things that
I didn't know existed before.

00:40.940 --> 00:46.413 align:left position:72.5%,start line:83% size:17.5%
Much of what lives in the deep is little known
or understood. This includes a group of

00:46.513 --> 00:51.818 align:left position:82.5%,start line:83% size:7.5%
animals few people have ever heard of,
some of which seem eerily like an

00:51.918 --> 01:00.026 align:left position:85%,start line:83% size:5%
outstretched hand reaching from the
grave. While others look like a field of flowers.

01:00.126 --> 01:04.631 align:left position:12.5%,start line:83% size:77.5%
For the first moment I learned
about crinoids I've been enthralled with them.

01:04.731 --> 01:07.067 align:left position:12.5%,start line:83% size:77.5%
I just think they're beautiful
organisms.

01:07.167 --> 01:10.570 align:left position:72.5%,start line:89% size:17.5%
Crinoids are the sea lilies and feather stars.

01:10.670 --> 01:14.040 align:left position:22.5%,start line:83% size:67.5%
They're one big group
of the major branch of animal life

01:14.140 --> 01:19.479 align:left position:82.5%,start line:83% size:7.5%
called the echinoderms, which includes
the sea stars, sea urchins, and sea cucumbers.

01:19.579 --> 01:23.883 align:left position:12.5%,start line:83% size:77.5%
Crinoids are often referred to
as living fossils because the forms that

01:23.983 --> 01:28.855 align:left position:80%,start line:83% size:10%
exist now are very similar to some forms
that existed during the age of dinosaurs.

01:28.955 --> 01:33.560 align:left position:77.5%,start line:83% size:12.5%
They've been around for a very long time.
Crinoids are found all over the world

01:33.660 --> 01:37.497 align:left position:87.5%,start line:83% size:2.5%
there are Arctic and Antarctic and
tropical crinoids. There are some species

01:37.597 --> 01:42.702 align:left position:80%,start line:83% size:10%
that are found as shallow as just below
the low-tide mark and there are crinoids

01:42.802 --> 01:45.905 align:left position:12.5%,start line:89% size:77.5%
in the deepest ocean trenches.

01:46.005 --> 01:48.508 align:left position:67.5%,start line:89% size:22.5%
My belief is these guys don't have natural deaths

01:48.608 --> 01:55.248 align:left position:80%,start line:83% size:10%
they died into predation, in other words
they will live virtually forever if you let them.

01:55.348 --> 02:00.987 align:left position:12.5%,start line:83% size:77.5%
What remains to be discovered
about these living fossils?

02:01.087 --> 02:05.087 align:left position:82.5%,start line:83% size:7.5%
What can modern crinoids tell us about
their ancient relatives?
