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.

The Occurrence of the Venus shell, Tapes literatus, in the Port River

A Summary of Recent Sunfish Sightings in the Encounter Bay/Waitpinga Cliffs Area

Sunfish sightings continued in the Waitpinga Cliffs area after the posting of my article Sunfish Sightings in the Encounter Bay/Waitpinga Cliffs Area. I thought it would be worthwhile summarising those sightings, like Dan Monceaux started doing in his article Sunfish sightings in South Australia. Dan had plans to upload those historic sighting accounts to the Atlas of Living Australia “so... 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

SA Rock Lobster Resource Review

I helped Reef Watch & Experiencing Marine Sanctuaries out at this year’s Science Alive! at the Showgrounds.

Back to the Breakwater for the Birds

I returned to the breakwater at Semaphore South today, mainly to search (unsuccessfully) for my lost glasses (during my recent kayak there). I visited the area twice today, once in the morning and again in the afternoon. The tide was still going out in the morning. I had a good look around the beach for my lost glasses. I was...
