Photograph taken by Daniela Wolf taken in Raja Ampat, Indonesia
Comment from Leslie Harris: The two curly structures look like the egg strings of a copepod which means the red & white thing is the copepod but it doesn't look like any I've ever seen. Very interesting!
Comment from the photographer: I found a different picture of this species. It was really small, and climbing on a scorpionfish. Maybe red curly thing is also a nudibranch?
