Crosslandia daedali from Bahia de Banderas

Dear Dr. Rudman,
I thought I would continue with some rare dendronotids from here. Crosslandia daedali is always a treat to find (I get to see about 2 or 3 every summer month).
These specimens I found at Los Arcos and Conchas Chinas, Bahia de Banderas, Pacific Coast of Mexico. They are 32 and 25 mm long at about 25 feet of depth.
In one of this pictures you can see very well the plumose gills of the animal and how well disguised it is to the Sargassum where I usually find it. I have not been able to identify which of the many species of hydroids living on the algae Crosslandia eats.
Congrats again on your work!

Dear Ali,
Thanks for these great photos. The certainly are well camouflaged on the brown algae. Have you checked the radula of any of these animals? Why I ask is the animal in your upper and lower photos have two well separated parapodial lobes much like in your earlier photos, but the middle photo shows and animal in which the lobes merge together on each side. This animal doesn't seem to have as many gills on the inside of the parapodia either. What I am wondering is whether you have 2 species here, perhaps a Scyllaea and a Crosslandia?
Best wishes,
Bill Rudman
