It apparently doesn't bounce you then. [20:25:43] Is this a bramble bamboo coral? [20:25:56] Have you already imaged today? [20:26:06] Got it - thanks. [20:26:20] Yes, we saw a smaller one earlier and got a zoom. [20:26:27] That would be currently called Isidella then. [20:27:20] Really nice to see all this diversity on the slope of Bear Seamount. The upper plateau is much more sediment laden with fewer corals. [20:27:27] nolanbarrett leaves the room [20:27:38] Some nice large Keratoisis coming up, likely D clade.

Looked back at video this dive for fishes. Two imaged. Large blue-gray fish hiding under carbonate rock = Diplacanthopoma sp., a viviparous ophidioform fish, cusk eel. Subfamily Bythitidae (viviparous brotulas). This fish is slow-moving and has a high affinity for crevices and caves at the base of rocky formations. Second fish images is the red gaper, Chaunacops coloratus, also called sea toads - and unfortunate name since gapers (a type of angler) are not closely related to toadfishes. [21:36:15] Gapers have a short lure which is not dangled in front of the mouth as a visual lure. Instead, it is speculated that the stubby illicium emits a chemical attractant.
