Understanding, enjoying and caring for our oceans
(This article is a re-write of one published in our 2006 Journal, because it was only one of the early drafts that was published in error and some of the intended information was missing. I attempted to rectify the error by having Part 2 published in our 2007 Journal. Now, […]
The contribution of underwater photographs to marine science by Steve Reynolds Society member David Muirhead contributes many, if not most, of his photographs to marine science. Most of them, if not all, are posted to iNaturalist. This includes everything that moves and many things that don’t (move). He even took […]
Return to Christies Reef by Steve Reynolds A small group of us visited Christies Reef on 11th October 2019. It was a return visit for myself, following up on my visit there earlier in the year. The three of us got to dive independently (unintentionally). My own dive time underwater […]

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 […]
I am a research associate at the California Academy of Sciences where I study the evolutionary relationships among seahorse, seadragons, and pipefish in the family Syngnathidae. I employ DNA sequencing, morphological characters, and underwater photography to gain a better understanding of these relationships which are largely unresolved in this family, […]
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 […]
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 […]
