This deep water sea star was found in the gut of a rockfish! Observation by Eric Austin Yee, who was cleaning a boat belonging to J&M Sportfishing. This species is found 150-1000’ deep according to Smithsonian echinoderm researcher Chris Mah, who stayed up late helping me with this ID. 🙏 Unfortunately the sea star was thrown overboard in 100’ water after its photo op.

And yes, it looks like a Cheez-it.

Pacifia goddardi was located on reef at a depth of 40 feet. Length was 0.5 cm. Water temperature was 53 degrees F.

To my knowledge, this sighting extends the southern range of this species from the Hyperion Pipe to the Palos Verdes peninsula.

I was excited to find this Babakina festiva nudibranch, but it took @jeffgoddard to realize the importance of the Candelabrum fritchmanii hydroid next to it (there are actually 4 in the the photo) and point them out to me!

Not the best photo, but we had a positive ID from the captain and naturalists on board. We were in about 7000 feet of water. There were 2-5 whales in the pod. By the time I was able to get the camera on them only one was still at the surface. What we saw were brownish, fairly small whales, with hard-to-see short, bushy spouts. The dorsal fin was far down the back. Too small (and brown) to be Minke Whales, and different in shape and behavior from any of the local dolphin species. Cuvier's were seen close to this spot last week. These whales were up for just a short time, and then dove, and had not resurfaced after twenty minutes of our waiting for them. I've been waiting 22 years to see this species.

@anudibranchmom, this is the one I was telling you about!

Found by my wife while low tiding along the breakwater.

I had identified this as a possible northern anomaly of Anadara similis (C. B. Adams, 1852) a tropical species found from Baja, Mexico to northern Peru. Perhaps someone with knowledge of this genus can confirm this or suggest an alternative identification.

This looks similar to an observation by @anudibranchmom from Playa del Ray, California. @invertzoo

Armina californica feeding on Renilla koellikeri was located on sandy substrate at a depth of 40 feet. Lengths were between 1.5-3 cm. Water temperature was 57* degrees F.

Note that a different measuring device was used for water temperature. This device was calibrated and found to provide a true measurement, so it is not necessary to add 4 degrees to find the true temperature as with my other observations. See my notes for details.
