Experienced amateur citizen scientist age 65 currently living in Normanville South Australia zip code 5204. Keen snorkeler and scuba diver without a shred of biass, a rare specimen indeed! (Case proof:-I'd almost lost interest in tropical diving.Been there done that, pretty boring after first few trips.The fish move but the drab stony corals dont.Then a recent Ningaloo trip softened my stance somewhat. But still,I remain fiercely temperate in iNat context! Ever dived a temperate algal rainforest ? There's no going back...it'll change you.(Also statistically a much greater risk of harm in tropics,with higher costs:cheap packages only tell half the story). The grossly under-researched temperate rocky reefs of Southern Australia fascinate me. The 'Great Southern Reef' is larger, contributes more to carbon fixation, and is more productive AND BIODIVERSE than any tropical reefs, including the GBR. 'Dive' and 'reefs' are almost synonymous at a community level ,so divers often bypass the 'full hand' of other marine benthic habitats that provide unparalleled opportunities here inThe Unique South.We have the world's most diverse near-shore temperate marine habitat choices ,and many are suitable for shore access.From shallow embayments to crystal clear rock pools nestled beneath cliffs- deep pools which can be safely explored even while massive swells hammer the outer ramparts in spectacular fashion.From remote rocky headlands with splendid platform reefs to mangrove mudflats,vast seagrass meadows.,sponge gardens, bryozoan reefs, you name it we've got it.Add in our surprisingly wide continental shelf with many offshore isles and WOW! Shore snorkeling's a euphoric thrill along our thousands of km of accessible coastline. Its increasingly recognised that Southern Australia has the world's best temperate marine biodiversity,and the world's peak marine endemism.Goodbye Galapagos! Go Figure...If our platypuses, roos, koalas echidnas,peak avian and botanical terrestrial diversity are any guide to what we've got in our temperate marine backyard,then the marine life frontier is right here.The proportion of species that are undiscovered, undescribed, or known only from 1-2 museum specimens beggars belief. Are you sad because we lack crocs and must pay for zoo pandas? I'm ecstatic . Life's ours for the making....eternity's waiting...☺
