Distribution map of Sulcanus conflictus by geographical zones
Australia: W, SE & E (Swan River estuary, Georges River, Brisbane River estuary,) & SW (Swan River, Hopkins estuary, Mahurangi Harbour), Tasmania, N New Zealand (Orakei Basin)
N: 8
(562) F: 1,6-1,4; M: 1,6-1,5; {1,40-1,60; M: 1,50-1,60}
Rem.: Estuaries; euryhaline (Salinity: 34 to 1,7 p.1000).
Boxshall & Halsey (2004, p.204) confirm after examination of material from the Swan River Estuary the presence from 1 inner seta on the inner margin of the 2nd exopodal segment of P2 to P4, and not 2 in the Nicholls' text (1945, p.209). After Bradford-Grieve (199 b, p.213), Nicholls records specimens from the Swan River differ slightly from the Georges River specimens in that their A1 extend beyond the caudal rami, endopodal segment 1 of P1 has 2 inner setae instead of 3, and there appear to be some slight differences in male P5.
After Newton & Mitchell (1999), the nauplii can be hatched from estuarine sediment samples, particularly in response to salinity changes, and concluded the presence of of dormant eggs, probably in diapause.
