I've noticed the clustering behavior you pointed out in T. Kenji's photo of N. subnivalis in a couple of other small white Noumea as well. Here is a somewhat fuzzy photo of three N. decussata clustered on a small chunk of their yellow sponge prey. It was taken at Enewetak Atoll, Marshall Islands. Pictures of clustering behaviour in N. simplex are in a separate message.

After mentioning 'clustering' I couldn't find a photo to refer to so your contributions are very welcome. While posting this message I also discovered that in your earlier message on Noumea decussata the animals in your photos all illustrate the other point I made about Noumea - how many species, when resting, fold their mantle on either side into a prominent fold.
