Denise's Pygmy Seahorse

Denise's pygmy seahorse is a small fish which can reach a maximum length of approximately 2.4 cm, which makes it one of the smallest representatives of the seahorses. This pygmy seahorse has a short snout, slender body with a prehensile tail. Its body is either completely smooth or provided with some polyp-like tubercles, in which case these are fewer and less developed than Hippocampus bargibanti. Its coloration ranges from yellow, more or less bright, to orange with often small dark spots and sometimes darker bands on the tail.

This pygmy seahorse has been reported from several locations in the western Pacific, including Indonesia, Vanuatu, Palau, Malaysia, the Solomon Islands and Micronesia. It can be found at depths between 13 and 100 m, generally hiding in fields of gorgonians (e.g., Annella, Muricella and Echinogorgia).
