Thanks Joe,
Since 'Hexabranchus' means 'six gills', perhaps we should call this Monobranchus. I can't say whether this is a development problem or predator damage. I'll add it to the abnormalities page.

An earlier message from Erwin Koehler [#2964 ] of an animal from the Gulf of Aqaba, with 4 gills, suggests that something may have a liking for these gills. In both animals there seems to be a 'stump' where each gill should be.
Best wishes,
Bill Rudman
