The Oyster Blenny, Omobranchus anolius

When I recently snorkelled at the Ship’s Graveyard in the North Arm of the Port River, I saw lots of blennies disappearing into holes on the river bed. They were much too quick for me to be able to identify them at all. Some of them seemed to have long-flowing eel-like tails. I struck it lucky when I returned back to shore and a blenny posed on a rock for me. I was quite surprised by the colour, shape and…

Jessie Hussey’s contribution to the knowledge of SA’s marine flora

According to the web page found at http://know.ourplants.org/news/jessey-hussey-inspires-school-teachers/  Jessie Hussey made a “significant and pioneering contribution to the knowledge of South Australia’s terrestrial and marine flora during the 1890s.

Snorkelling at Ochre Point

We’ve done some recent snorkels at Ochre Point (midway between Moana South and Maslin Beach North). The area is magnificent. David Muirhead and I weren’t able to dive there the first time we visited the spot due to less than ideal conditions. David returned back to Ochre Point a little later on, this time with Graham Short and Alan Noble. They were able to do some snorkelling there on this occasion. I went back there with David again sometime later on…

Snorkelling at Myponga Beach

David Muirhead and I have done some snorkelling at Myponga Beach recently. One of these trips involved us snorkelling in a large rock pool there whilst there were swells breaking outside the rock pool. It was interesting enough to maintain our interest for quite a while.   David took this photo in the rock pool We also enjoyed the rock-hopping necessary to reach the rock pool and even some rock hopping around it. More recently, we launched my tandem kayak…

Recollections of my first few dives

I did my basic scuba course test dive at Port Noarlunga jetty on 4th February 1978. It was the first time that I had used scuba in the sea. Wayne Farquhar was apparently one of the dive instructors on my course. I knew Wayne from my job at Harris Scarfe Ltd. Wayne heard that I kept marine aquaria and came to see them at my home. He told me about MARIA (SA) of which he was President and invited me…

“My Wheels” At Second Valley

I love to see “my wheels” when I dive at Second Valley jetty. It’s great when I come across them during my dives there. I’m talking about large cartwheels and ‘truck sets’ that are in the bay between the jetty and ‘boat shed island’. I described these wheels in my articles titled “The Existence of an ‘Underwater Trail’ at Second Valley Jetty”, “The Various ‘Jetties’ at Second Valley” and “More About the Wheels at Second Valley” in our 2011 Journal….

ID of pipefish found at Sellicks Beach

We recently received a request via Facebook from Robbert Alexander‎ to identify a pipefish species that he found on Sellicks Beach. Robbert sent us a photo of the pipefish and we told him that it was “Most likely Stigmatopora argus, the spotted pipefish”. We also gave him a link to the relevant web page for the Australian Museum ( https://australianmuseum.net.au/spotted-pipefish-stigmatopora-argus ).   Robbert agreed with our ID of the pipefish and then sent us several more photos of it. He…

The Taking of Wide-angle photos 1/2 Above Water and 1/2 Below Water

When David Muirhead sent some wide-angle photos 1/2 above water and 1/2 below water to  Scoresby Shepherd (incl. the above image), he received this response from him: – “I’ve always been enchanted by these strange pics – 1/2 above water and 1/2 below. I’ve no idea what sort of lens can do it!”   David Muirhead diving with camera in hand (Taken by Steve Reynolds) David sent Scoresby the following explanation: –  “For in- water use you need a combination…

A Few Finds From Around Coffin Bay

Herewith a few finds, most made recently near (the) home (of Brian and Bernadette Saunders of Coffin Bay) : Eggs sacs like balloons on strings, their sandy stalks attached below the sand’s surface. We had previously found larval sea snails in similar egg sacs but these were a little smaller (about 20 mm in length) so we opened one and extracted a larva. The microscope showed a little creature (less than 1 mm long) with red eyes and several pairs…

Swimming with Surf Sardines at Myponga Beach

by David Muirhead I snorkelled at Myponga Beach’s south-western rock channels again this morning (29th Jan 2017) with my daughter who expressed interest in accompanying me because she’s never been in the water there. (No suits, just bathers, booties, fins, hood, mask, snorkel, SPF30+ and Sea Life camera.) The water was clear for a change (it’s been a wet, wild warm season). Bit surgier than same time yesterday morning (tide still well in but ebbing both days, with entries around 1030 a.m.) Today’s…
