[[File:Paphies australis on rocks.jpg|alt=The off-white shell of a lone specimen of ''Paphies australis'' sitting on a background of grey pebbles|thumb|right|Bivalves such as ''[[Paphies australis]]'' are a significant portion of the paddle crab's diet.{{sfn|Wear|Haddon|1987|p=40}}]]
The diet of paddle crabs consists predominantly of [[Mollusca|molluscs]] (especially of genus ''[[Paphies]]''), [[crustacean]]s, [[fish]]es, [[Polychaete|bristle worms]], and [[algae]].{{sfn|Wear|Haddon|1987|p=41}}{{sfn|Fisheries New Zealand|2023|p=1038}}{{sfn|Davidson|1987|p=29}} Large ''Ovalipes catharus'' tend to feed less frequently
The flattened hind legs and streamlined body shape of the crab allow them to swim rapidly and catch faster prey,{{Sfn|Osborne|1987|p=3}}{{sfn|McLay|Osborne|1985|p=125}} and they have slender, tapered [[chelae]] which are well-suited to handling small molluscs.{{sfn|Davidson|1986|p=295}} Their chelae are dimorphic; the left is used for cutting while the right is used for crushing.{{sfn|Davidson|1986|p=285, 295}} The paddles also allow the crab to stabilise itself and balance on its third pair of walking legs when digging bivalve prey out of the sand.{{sfn|McLay|Osborne|1985|p=129}}
