A very educated audience here to be guessing nudibranchs! That is a Flabellina verrucosa, one of our most common aeolid nudibranchs on this coast. Their feathery branches change colour depending on what they've been eating (seasonally). There he's cruising around on a sea peach (Halocynthia pyriformis), and in the left corner you can see a larval crustacean attached the the surface as well. Sea peaches are tunicates (chordates) and are thus one of our closest relatives in the sea:
Here's a trio of F. verrucosa from earlier in the year feeding on some bryozoans attached to the Agarum cribrosum kelp:
The red reptile is the aptly named "Rainbow Boa", and that one is of the Brazilian variety. Brighter reds, and even worse temper! I have a Venezuelan at home, and she's a doll... you'd never think they were the same species.
The blue spiky things are "slime worms" which is a terrible name given the beauty that shows up when you see all their detail. They are very light and pressure sensitive, so any movement around them (or flash) and they disappear into their crevices and won't be back any time soon, you only get one shot!
Here's a small-polyped soft coral (Gersemia rubiformis) that you'll find on walls in areas of high water movement:
More to come another day
For the sake of bandwidth-challenged members, I'll start a new thread.
