Great, scalloped or smooth? How to identify a hammerhead shark

As a South Australian snorkeler, typically drawn to shallow, inshore waters, I haven’t had first-hand contact with hammerhead sharks. As a child I found them fascinating; their distinctive T-shaped heads an apparent freak of evolution. In 2014 my interest in hammerhead sharks was renewed. That year, Western Australia introduced a shark culling policy in response to a number of human... Read more

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... Read more

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...

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...

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... Read more

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... Read more

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... Read more
