Now this holothurian is starting to swim.
Looks like he wants to take off, but...
He hasn't gotten the clearance from traffic control yet.
He looks like he's doing a ballet.
A ballet dance.
So far in this expedition, we've seen a number of holothurians up off the seafloor.
There are holothurians that are benthic, that live most of their life on the bottom and can come up off the bottom temporarily.
And there are also pelagic holothurians that spend their whole lives swimming.
Don't see that view every day.
