An extreme close-up of a large nudibranch called a nembrotha. The photo was taken in Panglao Island, Bohol along the fabulous Alona Beach. He/she (they are hermaphrodites) was moving around quite a bit for a nudibranch, but was still for a moment and I got this sort of excellent portrait showing all of his/her beautiful colors.
colourful
yes and fluorescent too!
