00:00:05.720 --> 00:00:12.410
Exploring in this way is sort of like wandering
around in the dark with a flashlight moving

00:00:12.410 --> 00:00:17.260
around trying to find something that may or
may not be here.

00:00:19.200 --> 00:00:23.100
I think we'll just keep our distance from
that.

00:00:23.100 --> 00:00:25.560
I've never seen one of these live before.

00:00:27.240 --> 00:00:34.500
This is a six gill stingray, a Hexatrygon
bickelli, and it's a very unusual observation.

00:00:34.500 --> 00:00:39.140
We almost nothing about the biology of this
species.

00:00:39.140 --> 00:00:46.570
You're getting among the first videos of live
individuals of these.

00:00:46.570 --> 00:00:48.030
I think that might be an Etmopterus.

00:00:48.030 --> 00:00:51.650
You see the dark streaks on the side towards
the back.

00:00:51.650 --> 00:00:53.690
The light colored areas in-between.

00:00:53.690 --> 00:00:57.800
My guess is that it's a lantern shark.

00:00:57.800 --> 00:01:03.330
There are three known species in the genus
Etmopterus in the hawaiian island, but this

00:01:03.330 --> 00:01:08.420
one doesn't look quite like any of those three.

00:01:08.420 --> 00:01:14.010
Another ecological mystery, from the Okeanos
Explorer dives and puzzle to be solved.
