Port Jackson Shark Aggregations

Recent aggregations of Port Jackson sharks at both Port Noarlunga and Aldinga created much interest in this annual event. I was encouraged to review past articles that were published in our newsletters back in 2006. Our September 2006 newsletter included this article: – “Port Jackson Shark Congregations” by Steve Reynolds Large numbers of Port Jackson Sharks, Heterodontus portusjacksoni, will congregate...

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

Jean and “Kitty” Whyte (Daughter of shark attack victim died exactly 77 years to the day later)

“Kitty” Whyte was SA’s first known shark attack victim. In March 1926, she had been giving swimming lessons to some children at Brighton jetty when she was attacked by a 3-4m shark She was subsequently rescued by two men in a boat, but she apparently died on the beach.  I previously documented Kitty’s death in two past MLSSA Newsletter issues...

Shovelnose Stingarees

Fish identification can be tricky at the best of times. Then there are often new species that were not included in the old fish books. And the scientific names of species are often changing, and even changing back again. I recently revisited my 2016 article titled “Same Ray Seen Two Months Apart” (It can be found at http://mlssa.org.au/2016/01/09/same-ray-seen-two-months-apart/). It was... Read more

Same Ray Seen Two Months Apart

I believe that I saw the same stingray (or stingaree) at Port Noarlunga reef on two separate dives two months apart. During my dive there on 7th November 2015, I took these photos of a ray just right of the jetty:- It seemed to me that part of the ray’s tail was missing. Two months later, on 6th January 2016,...

Submission to SA Government re: shark cage diving locations in South Australia

To whom it may concern, Please accept this submission as our official response to the announcement that alternative sites are to be investigated for the redistribution of shark cage diving tourism. We understand that the proposed redistribution follows the absence of sharks from long established sites near the Neptune Islands, a phenomenon possibly caused by an orca attack, witnessed by...

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... Read more

Buried Shovelnosed ray, Glenelg by Dan Monceaux MLSSA

Nocturnal observations around Glenelg marina and jetty

While this weekend’s scorching hot temperatures kept my wife and I out of the sun for the most part, we couldn’t resist making a late night beach walk down at Glenelg. While the habitats there are highly modified due to breakwater and marina construction, dune removal for coastal development plus stormwater, Patawalonga and treated wastewater inflows, there remains an abundance...

White shark by Terry Goss

Great white shark sightings at the Glenelg tyre reef in 2014

A pair of divers from the Adelaide University Scuba Club came face to face with a White pointer shark while diving at the Glenelg tyre reef in South Australia on 9th November. Although the shark came a little too close for comfort for Jan Busch and Mark Sutcliffe, Jan was at least able to take a few photographs of it. Details... Read more
