Ardeadoris sp. 4 (in NSSI 2nd Ed)

The genus Ardeadoris has a number of similarly colored species. All have an undulating mantle margin. In this species the body is cream with a red marginal band. The posterior side of each rhinophore with basal orange line. The gill is white with orange markings at its base.

We don't know much about this species, but it has been found on shallow reefs to about 15 m deep. Let us know if you see it. We need to know what it feeds on.

Thanks for sharing Dave

Dave Cowdery is a retired bio-medical Engineer and is the inventor of the Alumina/Titanium hermetic feedthrough (1970) for implantable bionics and the first to introduce a Titanium casing. This invention created the first bionic implant (pacemaker) with a service life that could be measured in years rather than months and is the basis for todays huge multi billion dollar bionic industry. David's pacemaker invention and his critical contribution to the launching of the Cochlear hearing implant has recently been recognised in two authoritative books ( "Innovative and Intelligent Bioceramics in Translational Medicine" and "Alumina Ceramics-Biomedical and Clinical Applications").

David is a Divemaster with over 5,500 dives experience and is based near Byron Bay in Australia. David is also a keen competitive road bicycle rider covering over 400 km most weeks. Photographic equipment used Nikon D800 camera with DS160 substrobes.
