Remarks: First recorded from PNG by Whitley (1949a) who described it as a new species, Galeolamna tufiensis  ; considered a junior synonym of Carcharhinus amblyrhynchos  by Garrick (1982). Common throughout PNG and regularly caught in longline and coastal fisheries. Filewood (1973) listed the species C. tjutjot  (= ” menisorrah  ) Reef Whaler which is characterised by having a more pointed snout than C. leucas  , precaudal vertebrae more than 100, sometimes a fine interdorsal ridge, lower teeth cusps moderately slender; these characters align with C. amblyrhynchos  and, more importantly, 8 of the dried jaws identified as this species deposited KFRS from Filewood’s collection had the identification of Carcharhinus tjutjot  on the label. Carcharhinus tjutjot  belongs to the dussumieri  -sealei group and C. menisorrah  is also a name previously attributed to this group; the only member of this group in PNG is Carcharhinus coatesi  (see further detail below).
