Dear Maggie,
This is an interesting find, as it is one of a number of sightings of this species from the Sydney region and other parts of New South Wales - all in the last 3 months. What makes it so interesting is that this is a species which has been identified as Spurilla chromosoma, formerly known only from the Californian coast of North America. I am not 100% convinced that it is the Californian species, but your species, whatever it turns out to be,  has been recorded from Japan, Hong Kong and the west Atlantic, suggesting it is a 'tramp' species being distributed by shipping. These recent records from eastern Australia are the first of this species from this part of the world.

I am in the process of dissecting the larger of your two specimens to comfirm its identity and will post my results in the near future. Have a look at the other recent messages on this species attached to this page.
Best wishes,
Bill Rudman
