The Pigmy Seahorse is one of those few sea creatures right in front of me when staring at coral branches and will never notice. They are tiny like 5mm to 10mm in size and so well camouflag with the coral they live most their life. This coral is being lit by special lighting equipment that emphasises biofluorescence. I wasn't sure if the Pigmy would glow so I tried anyways as have seen a few photos before of a few variety that have so always worth taking that chance. The location is in Sabang, Puerto Galera, Philippines back in 2015.
