This is a target prawn (Sicyonia penicillata; Sicyoniidae) - thanks to Greg Jensen identification.
It belongs to Penaeoidea but not Penaeidae, and differs from other prawns in having uniramous, not biramous,
last three pairs of its pleopods. A field video of this penaeid prawn is here.

These slipper snails (Crepidula naticarum, Calyptraeidae)
were covering a moon snail shell occupied by a large hermit crab. These slipper snails are sedentary, and quite tightly attached, suspension feeders on plankton,
feeding with their expanded gill analogous to a clam's lifestyle. It is similar to another slipper snail,
C. norrisiarum (normally on a different host, Norrisia norrisii) but differs in that It
has a lopsided face, according to slipper snail expert, Dr. Rachel Collin. One can also carefully tug a preserved snail
away from its shelf under a microscope and, in this species, there is a deep depression under the apex, between the shell margin and where the septum (deck) attaches.

According to Wendy Enright, who gets to sample offshore critters for the City of San Diego, this large subtidal hermit crab is probably either
Pagurus spilocarpus or P. armatus, judging from the big eyes and touches of blue, not to mention not at all shy behavior. Crustacean expert, Dr. Greg Jensen, later identified
confidently as Pagurus spilocarpus.

A study to reconsider this assignment is underway (Eernisse and Draeger, in prep.). This one's solid color is unusual.

Dendrochiton gothicus (24), D. thamnoporus (2), Lepidozona scrobiculata (7), L. retiporosa (2), Callistochiton palmulatus (1), C. decoratus (1),
Leptochiton cf. rugatus (1; Eernisse et al., manuscript in prep.), and Deshayesiella cf. spicata (1; under investigation).
