Concerning message #19867:
Bill,
Here is a shell to go along with Nerida's 'miniham'. Her posting spreads the distribution of 'C.36' a bit further south. Last year, Michael Schroedl sent us a photo of the same species from Fiji.
The tail of this animal as well as one of our other minihams appears to be defensive in nature. At least, when attacked by an eye-dropper, the animal jerked back to it's point of attachment. This is when we found them on mats of cyanobacteria.
Locality: Toguon Bay, 7, Guam, 23 March 1988. Length: [shell 3.3 x 2.2mm], specimen 4.5mm excluding tail. Photographer: Carlson & Hoff.

I had always associated long sticky 'tails' with adaptations for 'hanging on' such as Stylocheilus longicauda living on floating algae in the open sea, but it of course makes perfect sense if some animals use a sticky tail for pulling the body away from danger. Very interesting
Best wishes,
Bill Rudman
