灰鯨 (Eschrichtius robustus)觀察者
anudibranchmom描述
Two adult grey whales repulsed a 6-hour attack by ~20 killer whales. Between 20-30 Transient Killer Whales from several matrilines (CA39s, CA140Bs (Louise's family), CA180, CA40, CA137, CA163 "Liner") teamed up for six hours, but were not able to take down two adult Grey Whales who showed their defensive experience - they stayed side by side, kept their vulnerable bellies up, whacked KWs with massive throws of their flukes, and generally outlasted these hungry apex predators.

Possibly an undescribed species rather than S. enosimensis: http://slugsite.us/bow2007/nudwk1236.htm

支鰓亞目 (亞目 Cladobranchia)觀察者
anudibranchmom描述
Found by @luanroberts. About 7 mm. Orange bands on white-tipped oral tentacles, orange bands on the white-tipped rhinophores, and white specks on the surface of the body.
Obelia and Tubularia (Pink-mouth hydroid) present elsewhere in the marina in small quantities, but didn't see it feeding.
Looks vaguely like the pale one in the left-side photo on Page 124 of Behrens & Hermosillo's Eastern Pacific Nudibranchs, 2005. Same individual as https://www.inaturalist.org/observations/91332884
Update: this hydroid https://www.inaturalist.org/observations/92299348 was the only hydroid on the boat bumper where it was found.

Oh man. I cannot id this one. It seems special though. I noticed it predawn. It was moving. As soon as my light shined on it, it stopped, sank and became flat.
*Siphon of a boring clam
*I'm referring to the specimen on the left.
