[21:49:05] a placiphorella [21:49:06] carnivorous chiton! [21:49:11] that's a carnivorous chiton [21:49:21] ChristinaConrath leaves the room [21:49:22] That chiton has a huge mantle [21:49:25] uses the veil to trap small crustaceans [21:49:28] they trap crustaceans under mantle [21:49:42] That is a new one for me! [21:50:02] LAT : 54.136005 , LON : -137.383229 , DEPTH : 1289.0425 m, TEMP : 2.55205 C, SAL : 34.45503 PSU, DO : 0.68314 mg/l, TURBIDITY : 1.2088 FTU [21:50:08] Lots of Farrea sponges [21:50:39] @scott there's a shallow one called Placophorella https://bodegahead.blogspot.com/2012/08/a-veiled-threat.html?fbclid=IwAR1JmKNZ2Send1_4uP_BN6E8aL_dZjdT4Ti_sI_MBF0TPQZaxBeieKmdo-E [21:51:22] Okay, so I can see ChrisM's link... How some but not others? [21:51:27] there are deep Placiphorella too [21:51:42] Placiphorella laurae is off california down to 1100m [21:51:54] Nice to know I can still be surprised by new things! [21:51:58] ChristinaConrath leaves the room [21:52:16] sarahfriedman leaves the room [21:52:55] I think the bamboo coral whips are new for today. Unless I missed some early. [21:54:15] nolanbarrett leaves the room [21:54:15] Pretty dense polyps [21:54:21] sarahfriedman leaves the room [21:55:03] LAT : 54.135956 , LON : -137.383263 , DEPTH : 1288.7417 m, TEMP : 2.54845 C, SAL : 34.45546 PSU, DO : 0.67313 mg/l, TURBIDITY : 0.9219 FTU [21:55:07] But the polyps are "soft" in the sense that the needles don't extend throughout the body wall, which allows for them to be so "floppy" [21:56:18] Good views. The skeleton is relatively thick, which suggests this is a whip for life, and not an early stage of a sparse branching colony. [21:56:20] Every time we zoom..I see those black blob brittle stars.. curious to see how abundant they are! [21:57:59]
