Parks Victoria Technical Series No. 79 Flinders and Twofold Shelf Bioregions Marine Natural Values Study a) b) c) d) Figure 48. Deep subtidal reef invertebrates in Beware Reef Marine Sanctuary: a) ascidian Botrylloides perspicuus, b) feather star Cenolia trichoptera, c) southern jewel anemone Corynactis australis and d) basket star Conocladius australis on a sponge. Photos taken by Friends of Beware Reef Marine Sanctuary. Fish The fish assemblages associated with Phyllospora communities of the Twofold Shelf Bioregion have characteristics typical of both eastern and southern temperate waters, and are therefore quite different to elsewhere in Victoria (Edmunds et al. 2010b; Williams et al. 2007; Figures 44, 45, 46 and 53). Wrasse and damselfish were the more abundant species at Beware Reef. Four species of wrasse, the blue throat wrasse Notolabrus tetricus, purple wrasse N. fucicola, Maori wrasse Opthalmolepis lineolata and rosy wrasse Pseudolabrus psittaculus are common (Williams et al. 2007; Edmunds et al. 2010b), although their abundance is variable between surveys (Edmunds et al. 2010b). The damsel fish, the one-spot puller Chromis hypsilepis and whiteear damselfish Parma microlepis are eastern warmer water species that occur in the MS (Edmunds et al. 2005; Williams et al. 2007; Edmunds et al. 2010b; Figure 49). Banded morwong Cheilodactylus spectabilis is also common at Beware Reef MS (Williams et al. 2007). Beware Reef MS has very high densities of the plankton feeding butterfly perch Caesioperca Lepidoptera, with schools of over 1000 being observed (Figure 50). High densities of butterfly perch are generally associated with reefs of high relief with extension into deep water, such as at Beware Reef (Edmunds et al. 2010b). The abundance of this species 101
Parks Victoria Technical Series No. 79 Flinders and Twofold Shelf Bioregions Marine Natural Values Study makes the MS distinct from other MPAs in the bioregion (Edmunds et al. 2005; Edmunds et al. 2010b).The rosy wrasse Pseudolabrus rubicundus, is also typical of higher relief reefs. Other fish observed in the MS are bullseye Pempheris sp., long-snouted boarfish Pentaceropsis recurvirostris, draughtboard shark Cephaloscyllium laticeps, sea sweep Scorpis aequipinnis, Port Jackson shark Heterodontus portusjacksoni, wobbegong Shark Orectolobus sp. and weedy sea dragon Phyllopteryx taeniolatus (Plummer et al. 2003). Fish diversity has been observed to be higher on the northern side of the reef compared to the more exposed southern side (Williams et al. 2007). a) b) Figure 49.
