Found at low tide in a rocky channel this egg-case was well attached by the tendril at one end to something below a covering of sand.
Also known as Swellshark or Draughtboard shark. The case was about 250mm long, squared at one end and tapered to a point at the other. Each end had two long, curly tendrils. The shark is a benthic zone species native to Australian waters. A very similar and related species is found in New Zealand.
An eight-armed carpet sea star with greenish grey colouring. The arms showed some red along the margins. The body pattern included small white scalloping and the central disc was a beautiful green.
The arms were well defined ending in thick rounded tips.
This sea star was about 50 mm across.
Spotted in a rock pool - intertidal rocky shore (Cape Conran) facing the Bass Strait. They occur all around the Australian coast.
This mass resembling worn coral was about 10 cms across. On the surface were crescent shaped structures which were the open ends of calcareous tubes constructed by tubeworms. They have clustered together and probably grown on a snail, completely enveloping it and forming a hard mass, as suggested by Audrey Falconer(Marine Research). The mass was partially covered with sand but red algae could be seen growing on the mass.
The tubes are built by annelid fanworms from the family Serpulidae. The worms have branchial crowns in two lobes, one of them has a stalked operculum (lid). The branchial croown form the gills and also helps to capture food.
The worm lives within the tube and retracts into the tube when in danger or when the tide is out, pulling the operculum down tight to shut the opening of the tube. A dense mass of tubes can form a microhabitat for other marine creatures. My thanks to Audrey Falconer ( Marine Research) for identifying this mass.
Spotted in a rock pool in an intertidal zone of a rocky shoreline ( Cape Conran, Victoria). These tubeworms are seen from Southern Queensland all along the southern coast to Western Australia.
A mollusc with a flattened body and eight distinctive overlapping plates that protect them from predators and crashing waves. This chiton was grey-green in colour, about 63 mm x 35 mm. The girdle encircling the plates had a snake-skin like appearance giving it the common name "snakeskin chiton".
These chitons were found along with barnacles, attached to the side of a rock in an intertidal rocky shore (Cape Conran) off the south coast of Victoria facing the Bass Strait.
This species is said to prefer rock surfaces in the mid-tide region, rather than under rocks in lower -or sub-tidal zones.
The anemone was about 50 mm with tentacles extended and floating in the water. Tentacles were numerous, translucent but dark green in colour and had pointy ends. The oral disc was covered by sand and therefore not visible.
Where the anemones were out of water, they looked like dark clumps studded with sand grains. Partially submerged anemones (pic 3) were interesting in that the submerged part had extended tentacles and the exposed part was curled up displaying a sand encrusted column. Long striations could be seen in the retracted column which was the same colour as the tentacles.
Spotted in rock pools - rocky intertidal zone (Cape Conran)
These mussels were about 40 mm long. The purple shells had black rims with thin curved lines.
They were seen in clusters and were of varying sizes.
Spotted on exposed rocks - rocky shoreline in the intertidal area ( Cape Conran, Victoria)
