Nudibranchs and other sea slugs of the Port River, South Australia

The Marine Life Society of SA was recently asked which species of sea slugs (which include nudibranchs) are found in the Port (Adelaide) River. We’ve only just started exploring the river underwater, so the list below is very much a work in progress. Prior to 2017, as far as we are aware, the river was largely unexplored (by divers at...

What to do with old fishing gear found while snorkeling or diving?

Divers and snorkelers often come across discarded or entangled fishing gear underwater. Unsurprisingly, the problem is most pronounced around rocky points or jetty structures where people regularly fish. Responsible divers do the right thing, and where practical, cut loose and bring ashore any gear they encounter… though one must be careful not to pierce one’s neoprene gloves, wetsuits (or worse:...

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...
