  • Maroga melanostigma Fruit Tree Borer

    13 Dec 2018-37.9,145.3Leuba Ridgway

    A smooth white moth with a wing span of 40 mm, with, as the name suggests two small spots of black on the wings. Surprisingly, the underside showed orange and black banding on the dorsal side of the abdomen and a white belly. The legs were covered with short orange coloured setae. Eyes and antennae were black. labial palps were rec-curved.

  • Rickenella spp.

    10 Jun 2018-37.9,145.3Leuba Ridgway

    Caps of this bright orange mushroom were no more than 10 mm with a deep central depression. Younger fruiting bodies were almost hemispherical, flattening out as the mature. Caps showed some striation and margins were wavy. Stipe was smooth and slightly paler than the cap. Could not get a shot of the gills. Possibly Rickenella fibula.

  • Cystophora torulosa

    01 Jun 2018-38.4,145.1Leuba Ridgway

    This attractive sea weed had a zig-zagging tough central stalk with small densely clustered bladder like blades, arising at points in the zig-zag. Some blades had a bifurcation. The whole body of the seaweed was a brownish green with dark brown tinges. Said to grow in the low intertidal and shallow subtidal rocky reefs with moderate wave action, to depth of 10 m. Spotted along the high tide mark on a sandy shore, along with other sea weeds - Western Port Bay

  • Gloiosaccion brownii

    01 Jun 2018-38.4,145.1Leuba Ridgway

    This pale reddish brown elongated sac-like structure with a club shaped tip and narrow base is part of a red seaweed which grows in a clump, attached to the sea floor by a discoid holdfast. The inside of the bladder appears to be filled with mucilage. This bladder was about 50 mm long. This seaweed can grow up to 16 cms in length. The outer walls of sacs growing in rough waters are said to be thicker than those in calm waters. The secretory cells lining the inside of the sacs produce highly viscous mucilage. Spotted along the high tide mark along with other sea weeds on a sandy beach - Western Port Bay. Occur in Seagrass beds upto a depth of 20 mts.

  • Thylacodes sipho Common Worm-shell

    25 May 2018-38.0,145.0Leuba Ridgway

    This coiled thin shell with pale orange bands is that of a marine gastropod/snail that lives in a coiled tube. The snails resemble tube worms (polychaetes) because of the structure but are in a different family. The tube is usually cemented to other structures. Unlike other snails, this species does not have an operculum or lid.

  • Electroma papilionacea Common Butterfly-shell

    25 May 2018-38.0,145.0Leuba Ridgway

    A bivalve with paper-thin shells and about 40 mm wide. It had broken orange bands radiating from the umbo (where the valves are hinged). A very fragile specimen that was surprisingly intact despite being blown about in the wind. The slightly flared part of the shell near the umbo (on the Lt side in Pic 1) is called the auricle or wing, giving the species it's common name.

  • Goniocidaris tubaria Thorny Sea Urchin

    06 May 2018-38.5,145.2Leuba Ridgway

    This slate-pencil sea urchin would have been about 50 mm across. It had probably just died and been washed ashore - still had most of its short thick primary spines and smaller needle like secondary spines. The primary photo is of the top side (aboral) and the second is of the underside (oral) with the mouth in the middle. Just visible in pic 4 is a triangular white tooth-like structure in the centre which is part of a complex dental apparatus called the "Aristotle's Lantern". The shorter spines were a deep red and the thicker ones were paler, some with deep red ridges. It is possible that a few long ones were broken at this stage. Spotted on the rocky ocean shore -low tide mark on the south coast. (Phillip Island)

  • Aulactinia veratra Common Green Anemone

    22 Mar 2018-37.8,148.7Leuba Ridgway

    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)

    13 Mar 2018-37.2,145.4Leuba Ridgway

    A black wedge-shaped beetle about 15 mm long with white specks on elytra and dramatically flabellate antennae. Legs were a deep brown with black colouring at the femoral and tibial joint. A slightly humped scutellum and head were also black. Spotted on a young eucalyptus tree in a small reserve. The larvae are ecto-and endoparasitic on other insect larvae, possibly of cicada. Commonly called feather-horned beetle.

  • Galeolaria caespitosa Intertidal Tubeworm

    22 Mar 2018-37.8,148.7Leuba Ridgway

    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.

      • Leuba Ridgway  Thank you for adding the ID to the database David and your message. Prior to posting here I sought help from the Marine Research Group of The Field Naturalists Club of Victoria. Audrey Falconer (an expert on Marine Invertebrates) provided me the ID. Also given the location where it was found, I believe the species to be correct. I also checked the Port Phillip marine life web site as it's very useful.

    22 Mar 2018-37.8,148.7Leuba Ridgway

    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.

  • Sypharochiton pelliserpentis Snakeskin Chiton

    22 Mar 2018-37.8,148.7Leuba Ridgway

    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.

    This moth had a wing span of 20 mm. Typical to this species, it stood on it's front legs holding it's up-curved abdomen in the air with the apices of the fore wings resting on either side. The wings were a mix of grey and brown with thin wavy lines. The costa had white markings down the whole length. Spotted under bright garden light. Unsure of the ID as there are a few with varying wing patterns and colour.

  • Hydroclathrus clathratus

    20 Jan 2018-38.4,145.1Leuba Ridgway

    A brown algae with a thallus (body) with multiple holes of varying sizes. The algae is said to be about 10 cm in diameter. But in the one that was washed ashore it was a loose mesh like a woolen hair net. The whole mass was compressible and soft. Found on the inter-tidal zone off Western Port Bay (Balnarring Beach). They are said to grow in the tidal zone. 'Hydro' = water, 'Clathrus' = mesh This species forms dense mats.

  • Aplysia sydneyensis Sea Hare

    20 Jan 2018-38.4,145.1Leuba Ridgway

    This sea slug would have been about 5 " in length. It had mottling of cream and brown. The ear-like sensory clubs or rhinophores and oral tentacle were withdrawn and the usually extended side flaps called parapodia were flipped back. The mantle and atrophied shell could be seen (pic 5) as a reddish radiating structure. I have the expert Mattt Nimbs to thank for the ID. He says "Definitely Aplysia. And yes probably A sydneyensis, there is a wheel like pattern of radiating stripes on the mantle that sits over the vestigial shell: a distinguishing characteristic of sydneyensis"

    1. Cathy Powers  Leuba - I am fairly certain that this is Dysbatus sp. 1. The lines match the description. It is in Moths of Victoria Part 5 and there is a CD page that details the difference between sp. 1 and D. singularis. The light has changed the colour of the moth which is usually grey.

    This moth had an attractive shimmer to its grey-brown wings. The wing veins stood out and were a distinctive brown. Each fore wing had two thin transverse black lines that together formed a band when at rest. Within the band was a small black crescent shaped mark. A narrow black line traversed the thorax along the anterior edge. Underside of wings were pale with dark sooty patches nearer the trailing margins. Wing span would have been about 30 mm. Spotted in a suburban garden. Probably attracted to lights at night. Thanks to Cathy Powers for the ID.
