Hi Johan...
well, not having found your ribbon worm in Two Oceans, I asked George Branch and Charles Griffiths and they both think it looks most like a European species called Tubulanus annulatus .. but it's never been seen here before so they'd be quite keen on getting a  specimen if that's possible... how often do you see them?
best wishes
Georgina

At first it was short but as it move it just got longer and longer

Thanks for all your help during the years

Hi Johan,

This appears to be Tubulanus sp., a Palaeonemertea.  A nice specimen! Tubulanus annulatus has been attributed to the SA fauna. It is similar in ground color and in having white rings encircling the body but I my best guess is that this is not that species, which so far always has 3 longitudinal white lines. I can detect only 2, apparently lateral, longitudinal lines in your specimen. It could be a regional variant or an undescribed species (or even a Heteronemertea; the rings are reminiscent of a couple of genera of heteronemertean but associated with longitudinal stripes is not; but I can't see enough detail of the head to be sure).

Best wishes,
Jon

Hi Johan,

My first instinct is "Tetrastemma", which is a huge convenience trashcan
of hoplonemertean species that probably represents several closely but
also distantly related genera. Please do send me some higher resolution
pictures.
