Aphelodoris sp. 2
Port Phillip Bay, Victoria. 25mm long alive. October 1978. PHOTO: John Fields.
Although not visible in the photo, this animal has a dull translucent white foot with a pale orange border. According to Burn (1989) who considers each species has a unique geographic range, this is Aphelodoris rossquicki, but it differs considerably from that species in colour pattern. It does however look quite like the animal I am tentatively identifying as Aphelodoris greeni, which is said to be restricted to Northern Tasmania.
