Congratulations Marek, your dorid nudibranch is our Spotting of the Day: "We felt we were overdue for another spectacular nudibranch! This Red-netted Goniobranchus (Goniobranchus tinctorius) is our Spotting of the Day. Nudibranchs are marine gastropod mollusks which shed their shells at the end of their larval stage. Goniobranchus tinctorius belongs to the family Chromodorididae, which contains some of the most colorful members of the animal kingdom. At the head region a pair of sensory tentacles called rhinophores can be seen. The feather-like structures at the rear end are gills".
