Conservation

  • IUCN Red List : Least Concern
  • Similar Species

    Differs from the Smalltooth Jobfish, Aphareus furca in coloration and gill raker counts. The Smalltooth Jobfish is steely-blue to purplish-brown above and silvery purple below, and has 22-28 gill rakers on the first gill arch (vs. 149-52 in the Rusty Jobfish).

    Etymology

    The specific name is from the Latin rutilans (= reddening, becoming red) in reference to the reddish colour of this species.
