Giant Tylodina perversa

Dear Bill,
Since last year I've seen many Tylodina perversa in Cerbere. There, the usual size of this species is about 3cm. And the largest animal I've seen before was less than 5cm in length. But during the last training course we saw a giant specimen of Tylodina perversa: 75mm in size. It seemed incredible !

Your comment about a 'giant' reminded me of one large T. corticalis which was found by a colleague here some years ago. It was also about twice the normal size. We don't know enough to be sure but I suspect that species of Tylodina only live for about a year, and these rare 'giants' are animals which have overwintered and are a year older than normal. - but that is just an idea, I have no direct evidence
Best wishes,
Bill Rudman
