This view emphasizes the serpentine flow of the leafy sea dragon trunk, with the tail curled to the left. The pectoral fins, used in a rapid but subtle rippling motion for sideways movement, are nearly invisible. From an overhead view the bony head protrusion is seen to have a V-shaped cross-section, with each eye having a protective spike, tapering into a structure that looks like a blade. Just above the eye are seen some small fluorescent green patches, similar to those I've seen on many leafy dragons, especially on the fleshy appendages. I believe these could be small growths of algae.  Identification: Phycodurus eques
