The pygmy seahorse (Hippocampus bargibanti) is so well camouflage that it was only just recently discovered, and “so extreme is this camouflage that the original specimens were only noticed after their host gorgonian had been collected and observed in an aquarium.” These tiny seahorses “are found only on gorgonians (sea fans) of the genus Muricella,” so they are specialists. No doubt, there may be more species of these little sea horses that remain undescribed.
