Opisthobranch of the Week Data
Doto sp. 4 is considered to be very rare on Okinawa's main island as I have collected only three individuals. The above featured animal was collected from an area of strewn coral rubble along with numerous hydroids. I originally made a "grunge collection" composed of several Zip-Loc bags full of miscellaneous invertebrates; one large bag contained several relatively large hydroid colonies. Several hours later at home while examining the material in a sorting pan, I found the featured animal, as well as two additional specimens from the same hydroid. The additional two collected specimens (the two were neither photographed nor measured) appeared to be identical, but smaller than the collected 10mm specimen.
In addition to Doto sp. 4, I've collected at least seven unknown Doto species from Okinawa's main island and I've featured a series of described and unknown Doto species previously on these pages. These Doto species are profiled on the following links:
