Nudibranch Garden scene
2 different Nudibranch species found close to each other. The one on the left is Goniobranchus sinensis and the other on the right at the background is Thecacera picta.
Am setting the ID to Goniobranchus sinensis because there's only 1 other post of it at JD for now :D
''Goniobranchus sinensis'' is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.
