Tentative: Sexy anemone shrimp (Thor amboinensis) is named for its unusually body movements, swaying its abdomen back and forth with flair. They normally are found among anemone tentacles but will scavenge fearlessly for meaty foods.- See here for source.

A lionfish is a venomous fish of the family family Scorpaenidae, which includes several genera of similar appearing fishes.

Fish-eating anemone
image
The fish-eating anemone, Urticina piscivora, eats small fishes or shrimps, but the painted greenling (see below) seems to hide among its tentacles similar to how clownfish hide within tropical anemones. (source) - See here for a study on its feeding and predator-avoidance behavior (it can detach if threatened by the leather seastar, Dermasterias imbricata)
image
The Christmas or painted anemone, Urticina greybelnyi, is a common northern species often mistakenly referred to as Urticina crassicornis. It is never buried in sand and its column is always free of attached pebbles or shells. - see here for taxonomic details.
image
Cribrinopsis albopunctata (formerly Urticina lofotensis or Tealia lofotenis) next to a giant green anemone, Anthopleura xanthogrammica- See here for discussion of the confusing taxonomic history and better images of this very beautiful and common northern sea anemone.

Spot prawn (Pandalus platycerus) is common from Alaska to California, but is in quite deep water (500 to 1600m) in the southern part of its range. - see here

Sabellid polychaetes (Annelida: Polychaeta: Sabellidae)

The horned puffins seemed friendly.
image
Members of the blood star genus, Henricia, are sponge-eating delicate seastars found in temperate or cooler seas worldwide (including deep water). The many West Coast species are the subject of ongoing collaborative studies by Prof. Eernisse.

A grunt sculpin, Rhamphocottus richardsonii, is the only species in the family Rhamphocottidae
image
Mosshead warbonnet (Chirolophis nugator) belongs the prickleback family (Stichaeidae). The decorations on its head provide camouflage to its head, which is normally all that is exposed when this fish sits in its normal position, sitting in a crevice, old shell, or bottle.

North Pacific giant octopus (Enteroctopus dofleini) is thought to be the world's largest octopus species, with an official record of more than 156 lbs. (71 kg) and an arm span of about 30 feet (nearly 10m). This is the aquarium's only octopus and seemed unusually active on this visit.
