I think this is a snakeskin chiton that had it's photo photobombed by the common triplefin. The second photo has the glove finger. Living in a tidal gut
I assume this is a snake's skin chiton but what is going on here? Is this in breeding form, repairing it's armour or what?? That second second segment from the left is certainly not 'same old' stuff. This may be S. sinclairii X pelliserpentis. Both are similar S. sinclairii lacking longitudinal ridging as in this specimen, both have snakeskin skirt, both have been mooted as one variable sp, however only one form can be found in some stretches of coast. The reason it may be a hybrid is S sinclairii lacks the radial nodules evident on this specimen.
