Long-nosed fur seal at Encounter-Bay by Emma Monceaux

Long-nosed fur seals hauling out at the Fort Glanville breakwater

I had a pleasant surprise on Friday afternoon, when I was treated to an intimate encounter with South Australia’s most notorious pinniped. I’m talking about Arctocephalus forsteri, the long-nosed fur seal; loved by many and detested by some. Previously known as the New Zealand fur seal, its common name caused some confusion in the community, as people falsely assumed that the species wasn’t native to Australia. In South Australia, its population is actually still recovering from intensive sealing efforts in the…

Port Hughes Jetty 2013 - Steve Reynolds

List of shore dive locations within 2 hours drive from Adelaide

I’ve always been flummoxed by the trend whereby divers who live in Adelaide continually revisit a handful of the state’s innumerable shore diving locations. While the popularity of Rapid Bay jetty, the rocky reefs of Second Valley, the soft coral encrusted columns of the Port Hughes jetty and the built and natural habitats of Port Noarlunga is not undeserved, I’ve compiled this list in the hopes that it encourages divers and snorkelers to branch out and try somewhere new for…

Oceanic Victor Pty Ltd/Tourism and Recreation/waters off Encounter Bay, 600m SE Victor Harbour/South Australia/Oceanic Victor Viewing Platform Proposal, SA Referral: 2015/7592 I would like to begin my personal submission by pointing out that this proposal by Oceanic Victor is the first time that any sea-cage aquaculture related operation in South Australia has ever been referred to the EPBC Act. Let me firstly commend the proponents for acknowledging the importance of EPBC referral, given the variety of sensitive receptors present in…

How South Australian senators in Canberra have voted on increasing marine conservation

The below table, compiled in October 2015 shows how South Australian senators have voted in Canberra on the topic of increasing marine conservation. Matters voted upon pertaining to South Australia include super-trawlers, threatened species protection, seismic testing for oil and gas off Kangaroo Island, Commonwealth marine parks and a moratorium on the issuing of oil and gas leases. Many of the remaining national matters related to the Great Barrier Reef in Queensland. The analysis and the methodology behind these results is explained in detail at…

Cuttlefish of South Australia

Before I embarked on the production of the documentary film Cuttlefish Country, I had little appreciation of the diversity of cuttlefish species which are found in South Australian waters. When I discuss cuttlebones with friends or strangers, I’m usually met with surprise at the revelation that cuttlebones found in beachwash along the South Australian coast represent not one, not two but several species of cuttlefish. It is also unfortunate that there is no single resource available whereby South Australian naturalists or beach combers…

European shore crab (Carcinus maenus) at Marino Rocks - Dan Monceaux 2015

Invasive marine species in South Australia

Since first learning about marine biosecurity and the translocation of marine species from one region’s waters to another via commercial shipping and recreational boating, I’ve come to recognise a few of our locally found invasive species. This summer I’ve added another invasive species to the list of alien organisms I’ve found while rock-pooling, beach walking or snorkeling along SA’s coast. The most conspicuous invasive to be found in SA (in my experience) is the European fan worm. Not one to keep a…

Juvenile flounder, Glenelg North - Dan Monceaux 2015

Confounded by flounder in South Australian waters

During a walk through the shallows at Glenelg North beach after 9.30 pm last night, in knee-deep water, Emma and I were delighted to spot a numbers of small (likely juvenile) flounder. The animals were each less than 10 cm in length and sported fine, uniform sandy patterns which allowed them to practically disappear on pale, sandy bottom. When startled by our lights or movement, the animals escaped swiftly, hugging the contours of the sandy ‘dunes’. On settling, they would sometimes shuffle into the…

Black Cowry (Zoila friendii thersites) at Port Noarlunga - Dan Monceaux

Black Cowry (Zoila friendii thersites)

Yesterday, while snorkeling at the Port Noarlunga reef in near perfect conditions I was fortunate enough to encounter a South Australian endemic gastropod mollusk, the Black Cowry (Zoila friendii thersites). The animal I sighted was perched quite conspicuously on a large yellow/orange sponge in about three metres of water. I later discovered that a photograph taken by Greg Adams of one in the midst of laying eggs (also taken at Port Noarlunga) was published in October 2014 by ABC news. I was first made…

Seen a shark in SA waters? Report it for safety and science

When I discuss sharks with divers or snorkellers, they tend to agree that shark sightings of any species are a rarity in SA- at least off metropolitan beaches and at popular dive sites. In something of an anomaly, a single Great White Shark (whether it was the same individual on both occasions is unknown) was encountered by divers twice this year at The Dredge. The wreck is located approximately 6 kilometres offshore in about 20 metres of water. On both…
