The wonderful and diverse syngnathids of Normanville, South Australia

I am a research associate at the California Academy of Sciences where I study the evolutionary relationships among seahorse, seadragons, and pipefish in the family Syngnathidae. I employ DNA sequencing, morphological characters, and underwater photography to gain a better understanding of these relationships which are largely unresolved in this family, and therefore is in need of a major revision which will help in the management and conservation of these fishes. Australia, and in particular Southern Australia, is a major hotspot…

Port Hughes Jetty 2013 - Steve Reynolds

MY LOVE OF JETTIES, SOME OF MY JETTY WORK , GRANITE ISLAND JETTIES & A LIST OF S.A. JETTIES BUILT DURING THE 1800s OR EARLY 1900s

I think that I first became fascinated with jetties when I first started scuba diving in January 1978 after visiting Port Hughes jetty. I did my first sea dive at Port Noarlunga jetty in February 1978. Although I had visited several piers whilst I was in England, it was mainly through diving in South Australia that my love of jetties grew. Diving led me to an interest in the history of local shipwrecks and jetties. My interest increased when I…

Buried Shovelnosed ray, Glenelg by Dan Monceaux MLSSA

Nocturnal observations around Glenelg marina and jetty

While this weekend’s scorching hot temperatures kept my wife and I out of the sun for the most part, we couldn’t resist making a late night beach walk down at Glenelg. While the habitats there are highly modified due to breakwater and marina construction, dune removal for coastal development plus stormwater, Patawalonga and treated wastewater inflows, there remains an abundance of life to be observed by anyone with an eye for detail and a nice bright flashlight. Emma and I…

The Stenhouse Bay Lookout Walk

During my Marion Bay trip in April 2014, my wife and I visited Stenhouse Bay. We enjoyed walking around the area, including the jetty there. A highlight of the day was a walk on the Stenhouse Bay Lookout Walk adjacent to the jetty. The Stenhouse Bay Lookout Walk is said to be a 2km easy walk that takes about 1 hour to complete. It is a loop walk that returns to the start near the picnic and information shelter by…

Port Hughes Jetty 2013 - Steve Reynolds

Nudibranch Discovery At Port Hughes Jetty

Hank van der Wijngaart, President of the Scuba Diver Federation of SA went diving at the Port Hughes jetty on Sunday 28th Dec 2008. He found a nudibranch on one of the jetty pylons* there. * (I prefer to call them ‘piles’. Pylons go up, piles go down.) Despite the surgy conditions there, he managed to take a reasonable photo of the nudibranch. Hank thought that it might have been a specimen of Hypselodoris infucata but wanted expert confirmation to be certain of…

Leafy Sea Dragon

Tumby Bay Jetty Dive

Jenni and I had a few days R and R at Port Lincoln this week so I took my gear, hoping to get a few dives. The shore/jetty dive prospects and viz at Whyalla, Cowell, Port Neill and Arno Bay varied from poor to “possibly just o.k. but let’s try the next town.” Finally at Tumby Bay, the last town before Port Lincoln, both the viz and the jetty access looked adequate so in I went, complete with a ‘Seachange’…

European fan worm

Sabellid Worm Discovered at Port Noarlunga

Mary Anne Stacy of the Port Noarlunga Aquatics Centre recently discovered an unusual fan worm on a pylon of the Port Noarlunga Jetty. Suspecting it to be a Sabella worm (a species introduced from European waters in ships’ ballast) Mary Anne organised for it to be identified. Her fears proved to be correct. This is especially disturbing as although this highly competitive worm is particularly abundant in the Port River area, they were not thought to have spread further south…

Brighton Jetty South Australia - David Muirhead

Brighton Jetty clean-up dive and stormwater sump unveiling

We held our Clean Up Australia Day dive at the new Brighton jetty in March this year. There were strong south-westerlies and the seas were rough. We only had four divers but several other members were keen to assist with the clean up. The four divers entered from the shore and swam to the outer end of the new jetty with their hessian bags to fill. Not all of the bags were brought back, however. My first (full) bag was…

Port Minlacowie jetty 1916 - State Library of South Australia B32231

Port Minlacowie Jetty

Over Easter in 1988 twelve society members dived at the site of the old jetty at Port Minlacowie. We followed the stumps of the old jetty piles out to the end. We managed to find some broken bits of old steamship crockery and even an intact crew plate. The jetty had been built in 1877 at a cost of 4,759 pounds. It was 1150 feet long, Government owned and controlled by the Minlaton District Council. It was destroyed in 1971…
