Underwater I was under the impression that this seahorse was a H. kuda, possibly due to the speckling on the face, but when analyzing the photographs the ID was changed to H. trimaculatus. I have uploaded clearer, cropped pictures of the head. On these photographs it has become more apparent that this seahorse has a backward-pointing curved cheek spine (although the curve is minimal) and a sharp eye spine (absent on H. kuda). The distinctive, "smooth" coronet of H. trimaculatus (compared to the back-raking coronet of H. kuda) is also clear. After having consulted with my colleagues and compared with other photographs of previous sightings of both H. trimaculatus and H. kuda, we strongly feel that this is a Three-Spot Seahorse, Hippocampus trimaculatus.

Thanks for adding the extra croppped photo of the head. Upon seeing the details of the hook-like cheek spine and visibly low coronet, I would tend to agree with your identification, as well.
