Sagaminopteron ornatum from South Australia

April 28, 2003
From: Alex Suslin

Accessed your site to get more info on Sagaminopteron ornatum, having seen one whilst scuba diving at Port Noarlunga Reef, some 30 kms south of Adelaide, South Australia. They used to be common there several years ago, until off-shore dredging badly silted up the reef. This was the first one I've seen since then, so hopefully, it may be a harbinger of the reef's recovery.

I note that under "Distribution", you include "...east & west coasts of tropical & subtropical Australia." It is also found along the temperate south coast, where water temperatures vary seasonally from about 10 - 20 degrees centigrade.

Confirmation of this critter's temperate water distribution can be found in
• Shepherd, S.A. & Thomas, I.M. (1989) Marine Invertebrates of Southern Australia Part II (South Australian Government Printing Division).

Thanks Alex,
You are of course correct. I certainly know of records from South Australia but am not sure of any finds in Victoria and Tasmania. If anyone has reords from there I would be most interested.
Best wishes,
Bill Rudman
