Gastropteron bicornutum Baba & Tokioka, 1965
Gastropteron (meaning winged stomach) are small cephalaspideans with an internal shell. Internally they lack a gizzard but have a radula. Gastropteron have a tube, rather than funnel, shaped siphon. There at least a half dozen undescribed species in the Indo-Pacific.
Talk about cryptic - it is hard to imagine how Lindz spotted this little devil. Man does its speckled coloration blend in with the bottom sediment. Although difficult to see here, there are two conical appendages on the posterior shield and an elongate filament on the posterior end of the foot.
This species is widely distributed throughout the Western Pacific Ocean and grows to about 15 mm in length.

On the photographic front, the only reason she ever took it up was purely to document what she saw when diving. She started with a second hand Nikonos II, then a Nikonos III and later progressed to a Nikon F3 in an Aquatica housing only moving to digital in 2011. However she also became an accomplished photographer of land & air wildlife, human life events, of capturing special moments. And yet still her first love remains with marine life, especially opisthobranchs.
Having dived in many areas of the world including UK, the Mediterranean, (Spain, France, Corsica), Red Sea, Bahamas, USA (Florida, California, Hawaii), St Lucia, Montserrat, South Africa, Madagascar, Brazil, Fiji, Tonga, French Polynesia, the Tukang Besi Archipelago, SE Sulawesi, Lindsay now spends most of her time in Indonesia diving in places such as Bali, Alor, Lembeh as well as Komodo, Flores, Sumbawa, but has also recently ventured further afield to the species-rich Philippines.
As some of you probably already know, Lindsay spent several seasons in the mid to late 1990s in the Wakatobi National Park islands (Tukang Besi Archipelago, SE Sulawesi, Indonesia) with Operation Wallacea. I am sure it is there that she perfected her technique of non-invasive underwater photography, something I will never master. Lindsay is able to photograph with a 105 mm lens and Macromate wet diopter while hovering about the subject without actually settling down on the seascape. Once more, she is able to do this with macro and super macro subjects. The results are amazing as the reader can see.
Lindsay was a prolific contributor to Bill Rudman's Sea Slug Forum when it was still an active site but she continues to look for and photograph opisthobranchs of all kinds sharing her finds with us.
