Figure 3. Generalised Mixed Yule Coalescent (GMYC) Bayesian topology depicting the phylogenetic relationships of Octopus tetricus (east Australia and Tasmania), O. cf. tetricus (Western Australia) and O. gibbsi (New Zealand).

Analysis is based on three concatenated partial mitochondrial genes (COI, COIII and Cytb). Three species clades were supported via GMYC analysis; East Australia and New Zealand (red) and Western Australia (purple and black). Node labels reflect locations represented by individuals contributing to node (Western Australia, 1 = Mandurah, 2 =  Woodman's Point, 3 =  Albany, 4 =  Cape Le Grand, 5 =  Esperance; East Australia, 1 =  Wallaga Lake, 2 =  Port Stephens, 3 =  Narooma).
