Description

New one to me! This crazy nudibranch was not teeny -- about 1" long. Cream body with brown speckling and cool yellow lines. Large foot. Rows of gills like Dendronotus? Oral tentacles flicked up and down like a cockatoo's crest. BUT THE WEIRDEST THING were these crazy long flowing 'streamers' coming from the top of each rhinophore sheath - kind of looked like worms, though clearly attached and marked like the rest of the body (cream with brown specks). Found on Tubularia. Invasive? Video: https://www.flickr.com/photos/30314434@N06/25521619833/in/dateposted/

UPDATE 5/16/2016: Here's the very nice video that the California Academy of Sciences created about this guy: https://www.facebook.com/calacademy/videos/10154157032862311/
