Often confused with Hippocampus bargibanti, H. denise wasn’t recognized as a different species until 2002. It’s named after Denise Tackett, the underwater photographer that brought attention to its differences from H. bargibanti, including smaller size and lack of tubercles. It was originally believed to be the juvenile form of H. bargibanti. Closer inspection revealed it is in fact a seperate species.


Found at 13–90 m depth; it lives on seafans identified as Annella reticulata, Muricella sp. Echinogorgia sp.
