What are these?

[Burner]

I saw several things that I didn't know what were on a recent dive at point lobos.
Any ideas?

Is the purple algae growing on the fish or the fish's own camo?

1) lined chiton.

2) Don't know.

3) Looks like a sculpin; fish's own camo.

Where's point lobos?

 

[Burner]

Thanks.
Point lobos is by monterey, ca, its a state park and usually has excellent diving.

Thanks, I figured it was somewhere on the west coast.

The last picture looks like a Great Sculpin but even after staring at the book for a while, I'm still not positive. But I'm pretty sure it's a sculpin, someone else might have a better idea of what type. I haven't been able to find the item in the second pic though.

The second one looks sort of like a nudibranch but its all fuzzy. Took the picture because I had never seen it before. Hopefully somoene will know what it is

A little more info on the lined chiton. This is a fairly rare chiton, and one of my favorite things to search for when tide-pooling. I first heard it refered to as a "rainbow chiton" in 1990 by a marine biologist when I accompanied my daughter on a field trip to Pigeon Point lighthouse. The biologist had the entire class search for one in the tidepools just north of the lighthouse, and he was very excited when one of the kids found one. He said he had never found one before, and he visited that spot weekly leading field trips.

Anyway, I was at Pt Lobos last month myself and saw them in the inner bay area (as I was heading in). They are really beautiful (great picture btw).

So here are a couple links for more info on them.

Thanks for the info

The second one could be some sort of sea cucumber.

Nudibranchs usually have gas exchange protrusions located dorsally on the anterior and poster...

No promises though!

The second one... hmmm.

1. Algae. There are many species of calcareous and filamentous macrophytes that share this morphology.

2. Bryozoan. Ditto.

3. Polychaete. Don't see any parapodia though.

I've never heard of a "fuzzy" nudibranch before, nor a sea cucumber with a filamentous epidermis. Did you poke the thing to see if it was attached or not? Did you feel it? These are valid diagnostic measures.

 

[Burner]

nope I didn't touch it at all
