A Few Finds From Around Coffin Bay

Herewith a few finds, most made recently near (the) home (of Brian and Bernadette Saunders of Coffin Bay) : Eggs sacs like balloons on strings, their sandy stalks attached below the sand’s surface. We had previously found larval sea snails in similar egg sacs but these were a little smaller (about 20 mm in length) so we opened one and extracted a larva. The microscope showed a little creature (less than 1 mm long) with red eyes and several pairs…

Victorian marine worm I.D.

Early April 2016, we received an email message with the subject heading “Possible new species”. The message read (in part), “I was just went down Shoreham Beach with my family for a walk through the reef and stumbled across a strange creature. We were able to get a good quality video of it and thought I could send to you. We have previously sighted it three years ago at Mushroom Reef but wasn’t able to get it to any professionals….

Warning of hefty penalties for reef picking

That heading comes from PIRSA as part of a warning to fishers regarding rules for removing organisms  from intertidal reefs in SA. Reef Watch says that it gets quite a few reports from members of the public who have observed people taking organisms off intertidal reefs. The taking of marine organisms from intertidal reefs was banned along the shore of Gulf St Vincent (from Brighton jetty to Cape Jervis) in 1995. Details of the ban were mentioned in our April 1995…

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 of life to be observed by anyone with an eye for detail and a nice bright flashlight. Emma and I…

A Swimming Anemone’s mistaken identity

The unusual form of the Swimming Anemone was recently mistaken for a bubble coral. Fortunately the Marine Life Society of South Australia’s expert eyes picked up on the error and politely set the record straight. Invertebrate blogger and author of Aristotle’s Lantern Heather Lynn initially suggested on Facebook that the following photo was beyond its known range of distribution. Guerilla Bay in NSW, Australia (southeast coast). Photo copyright 2014 by Vera Kurz Heather’s post on Facebook read: “My lovely friend and…

Althorpe Islands Google Earth 2012

The Althorpe Islands Group Visit, 2004

On 29th Feb. 2004, the second of what is now an annual expedition to explore a South Australian island group, began with great excitement at the Althorpes island group. The last trip was to the Nuyts group and next year it will be the Investigator/Sir Joseph Banks group. The Althorpes are approximately 8 km SW of Innes National Park and can easily be seen from the mainland of the Yorke Peninsula. Althorpe Island has a long European history with its lighthouse…
