[19:31:11] These black corals look like the Dendrobathypathes/Parantipathes from this region that are so hard to separate (even based on genetic data) [19:31:29] Tina: Parastenella perhaps [19:31:38] polyp shape looks similar but colony morphology is different.

Both have those large eyes, plus enlarged nostrils with large chemosensory nasal rosette inside. There is a chin barbel which in both species is often kept in contact with the sediment, that barbel is peppered with taste buds and tactile sensory organs. C. acrolepis also has the outer ray of the pectoral fin elongated barbel like, and is likely similarly equipped. Finally, there is the lateral line that senses vibrations and water displacements in the near field. Note that in both species the anterior 2/3s of the body is held very straight, using only the tapering tail section to swim with. That enables left vs right signal matching by the two lateral lines. Nice combination of multi-capable sensors for both near-field and far-field detection of prey and predators. Oh - I forgot to include hearing. Some macrourids can produce and detect sounds, using the swimbladder at a gas-filled receiver and ampl [19:37:49] LAT : 54.753939 , LON : -156.527231 , DEPTH : 2290.425 m, TEMP : 1.86727 C, SAL : 34.59343 PSU, DO : 2.06907 mg/l, TURBIDITY : 1.1905 FTU [19:38:03] seanrooney leaves the room [19:38:24] kennethsulak leaves the room [19:41:18] seanrooney leaves the room [19:42:21] did you close up these small sticks?
