The front part of the pectoral fin, those fan-shaped things on the side, have thickened…

00:00:16.843 --> 00:00:19.980
And the fish actually uses those to walk around on the bottom.

00:00:20.604 --> 00:00:25.830
So those things that you see under the fish, they’re like little thin legs that are actually part of the fin.

00:00:26.599 --> 00:00:32.800
They are really interesting fish with a lot of unusual morphological features for life on the seafloor,

00:00:32.900 --> 00:00:34.000
hunting for little invertebrates, worms and other things.
