Another look at H. terramtuentis...you can see in this photo that the gill tuft can be retracted for safety.

Another Gold lace nudibranch (Haigerda terramtuentis), this one is feeling a little more bold--notice the gill tuft is fully extended. However, the rhinophores at the front are tucked in a bit...just being cautious, I guess.
