The small congolli that I found ‘belly up’ at Myponga Beach

I recently collected a small congolli that I found effectively ‘belly up’. The small congolli effectively ‘belly up’ (Taken by David Muirhead) Actually, it was lying on its side, on the shallow bottom towards one sandy rubbly bank of the moderately briskly outflowing but very narrow rivulet. The small congolli lying on its side, on the shallow bottom  (Taken by David Muirhead) The rivulet, barely 2 metres wide at that point, was running across the beach towards the sea, since the tide was out…

Pipefish encounters: One genus, two species, endless entertainment

Encounters of the kind below are not what most of us expect when at the beach for a swim and a bit of relaxation on a nice summer day. Which adds a special touch, for me at least. You can wade bare-footed at knee to waist depth off almost any white sandy beach in Gulf St Vincent and Spencer Gulf and see several species of pipefish that specialize  in hiding in and around the edges  of those dark patches of seagrass detritus that are…

Sternum from a Little Penguin found on Largs North beach

A piece of bone that I found whilst walking on Largs North beach this month has been identified as being from a Little Penguin. I took a couple of photos of the bone, which I first thought could have been shark cartilage. I posted some of these photos on Facebook, seeking identification of the creature that the bone may have come from. My photos created an interesting debate on Facebook. The end result though, was that the bone was thought…

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…

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…

Victorian marine worm I.D.

Early April 2016, we received an email message with the subject heading “Possible new species”. The message read (in part), “I was just went down Shoreham Beach with my family for a walk through the reef and stumbled across a strange creature. We were able to get a good quality video of it and thought I could send to you. We have previously sighted it three years ago at Mushroom Reef but wasn’t able to get it to any professionals….

Warning of hefty penalties for reef picking

That heading comes from PIRSA as part of a warning to fishers regarding rules for removing organisms  from intertidal reefs in SA. Reef Watch says that it gets quite a few reports from members of the public who have observed people taking organisms off intertidal reefs. The taking of marine organisms from intertidal reefs was banned along the shore of Gulf St Vincent (from Brighton jetty to Cape Jervis) in 1995. Details of the ban were mentioned in our April 1995…

ADELAIDE & MOUNT LOFTY RANGES NATURAL RESOURCES MANAGEMENT BOARD’s 2014-15 ACHIEVEMENT REPORT

We recently received the latest Achievement Report from the Adelaide and Mount Lofty Ranges Natural Resources Management Board (AMLRNRMB). The 2014-15 Achievement Report has now been filed alongside reports for the past two years (mlssa 2321). According to Prof. Chris Daniels, Presiding Member for the AMLRNRMB, 2014-15 “marks the first year of delivery under the board’s new 10 year strategic natural resources management plan for the region”. A glance through the report reveals sections on topics such as biodiversity, coast…

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…
