They're pretty much all guts, foot, teeth and maybe a bit of shell. Snails, limpets, octopuses or giant squid: they're all a kind of mollusc. You'll find one in almost every ecosystem in the world. 

Sydney University's Professor Ross Coleman specialises in limpets and knows all his molluscs pretty well. He takes us from the Liverpool docks, to Blackwattle Bay, to the weirdest of mollusc sex.
