The Port River – over 100 marine and coastal species and counting

I was first inspired to pay more attention to this often overlooked ecosystem by the discovery of the upside-down jellyfish, Cassiopea sp. there in 2016 by MLSSA president and area resident, Steve Reynolds. My personal explorations soon followed, beginning at Garden Island. There, a snorkeller can easily step into the water and explore several contrasting habitats within tens of metres:... Read more

South Australian marine biodiversity explodes onto iNaturalist.org

Marine Life Society of South Australia members need no reminding of the wonderful diversity of species present in our state and commonwealth waters. But how widely known is this out in the wider community? Up until the late 2000s, I would argue that local familiarity with marine ecology was severely limited. Those practising in specialised niches of scuba diving, marine... Read more

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...

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
