Robe, a South Eastern Wonder

11 Apr

Dear Reader:

It is early evening and I am walking along the beach looking for traces of animals washed up on the high tide. An old 4WD is slowly making its way towards the far end of the bay; probably some fishers preparing for an evening’s angling.

I am exploring some of the terrain in the state’s south east around Robe. I have been here on several occasions; as a marine science student examining the difference between marine life in this cooler thermocline and later as a snorkeler catching crayfish. The region is significantly different to Adelaide’s coastal environment. Not only is the water cooler and deeper close to the shore but also the limestone nature of the coast makes for quite different seascapes.

The charming coastal township of Robe is a lovely destination. The centre of the cray-fishing industry in South Australia; it is built around a sheltered marina. The town is a mixture of heritage buildings converted into small businesses such as cafes, craft shops and accommodation and some later modern residences and shops. There is an excellent caravan and camping area and the town is close to wineries, coastal conservation areas and farmland. All of which make it an ideal tourist destination. 

 

Sheltered marina

Nearby Nora Creina Bay is a perfect example of the rugged limestone coast which the region is named after. The rocks are sharp and pitted with hardy coastal plants clinging to any area which is sheltered or can trap water. Below the surface of the bay lies a myriad of small caves and crevices that support an abundance of marine life. There are holiday shacks in the area and a sheltered bay where cray boats often anchor.

Even the drive down to Robe was a wonderful experience as I was able to enjoy the wonders of the Coorong National Park which flanks the highway for around 100 kms. There are numerous trails that wind into the area which is characterised by shallow lagoons, steep sand hills and low scrub. These iconic environments host a wide variety of wildlife and I was lucky enough to see numerous birds of prey and several different reptile species as well as a diverse selection of wading bird species that migrate here to feed during the harsh northern hemisphere winters.

The sun has almost disappeared and the beach is empty and to be perfectly honest it is getting just a little chilly. It is definitely time to head back into town and try some of that fresh caught cray washed down with a local wine.

Cheers and stay safe in these unpredictable days

Cuttlefish Meeting

24 Feb

More Cephalopods on the Reef

Dear Reader:

I am working my way patiently along the edge of the Noarlunga reef-on the shallow side near the jetty. The water is no more than a couple of metres deep and surprisingly clear. Small schools of mullet are congregating near the surface, their silver sides reflecting the light with sudden bright flashes. Just below me there are several recesses that cut under the rocks and I can see some movement in one: perhaps a leatherjacket or even some bullseyes. I swim down and hold onto a nearby rock until my eyes adjust to the light. To my delight my encounter is a little more exotic, a giant cuttlefish is hovering above the sandy substrate patiently waiting for some unfortunate critter to come near its temporary lair.

 

 

Giant Cuttle (Sepia apama)

Length: mantle or body to 50cm.

  • Lives around reefs and over seagrass meadows
  • Hunts fish and crustaceans
  • Gather in winter in large groups to mate
  • Sexual reproduction and females attach clusters of eggs inside caves and crevices
  • Cuttles die shortly after mating
  • Can change colours rapidly to blend in with surroundings or display during courting
  • Like squid and octopus they can expel ink

Cheers

Over the next few months I will be writing a book about the wildlife of the Fleurieu Peninsula. My posts will reflect the research I am doing and provide more detailed information about each animal that I encounter.
