The new nocturnal foraging patterns regarding Centrostephanus varieties was suggested to-be a solution to prevent date effective predatory fishes for instance the wrasses Achoerodus viridis and Notolabrus tetricus ( Nelson and you can Vance, 1979 ; Andrew and Underwood, 1989 ; Andrew, 1993 ; Gillanders, 1995 ; Ling ainsi que al., 2009b ; Ling and you will Johnson, 2012 ). rodgersii is important getting survival of predators from inside the protected parts opposed that have fished reefs ( Ling and you will Johnson, 2012 ). Large predation out of C. tenuispinus including occurs in protected places where new wrasse Achoerodus gouldii preys about this varieties ( Create and you can Vanderklift, 2011 ).

C. rodgersii plus succumbs so you can nocturnally energetic predators, for instance the Vent Jackson shark, Heterodontus portusjacksoni and the stone lobster, Jasus edwardsii ( McLb ; Ling and you can Johnson, 2012 ). This new east stone lobster, Sagmariasus verreauxi, can feed on ocean urchins however the giving ecology for the types was poorly demonstrated. Numerous species of reduced predators and wrasses, octopus, and you can a collection out of micro-carnivores co-exists with C. rodgersii and so are potential predators with the quick adult and you may teenager C. rodgersii, but you’ll find nothing known of their feeling.
