This is a Phyllodesmium poindimiei . I found it around 20m deep, moving along the sand. What made is really stand out was what I saw as I started to take some extreme close up shots.
As you can see, the nudi’s body seems to be filled with small white balls. What was even more extraordinary was that some of the balls, the ones running along the bottom of the nudi, were rolling back and forth!! This is something I have never seen before.
After some investigation I found this out from renowned nudi expert specialist Terry Gosliner. Here’s Terry’s answer “It is definitely P. poindimei and I think they are ovotestis follicles that have somehow become dislodged. The animal has lost a lot of cerata and had an encounter with some predator. I suspect they somehow got dislodged during that interaction.”
So there you go,,,it’s ovotestis follicles became dislodged!!!
