Ok - as promise, a new species of nudibranch to add to my list... Trapania dalva. There are pretty small nudibranchs only ranging in size up to about 10-12 mm (less than a half inch). Their white rhinophores and gills give them the appearance of detritus on the sponges that they tend to be found on.

Technical Data: Canon EOS 7D, Canon EF 100mm f/2.8L Macro IS USM, 1/200th sec at f/8. Image Stabilization on. ISO 400. Ikelite Housing and Port and Ikelite 161 Strobe in TTL Mode. Raw conversion and cropped in Photoshop CS5.

Thanks for stopping by.
