The first pygmy seahorse known to science was "Hippocampus bargibanti". At least six more species were named after 2000. The first species discovered lives exclusively on fan corals and matches their colour and appearance. So effective is pygmy seahorse camouflage that it was discovered only when a host gorgonian was being examined in a laboratory. In 1969 a New Caledonian scientist, Georges Bargibant, was collecting specimens of Muricella spp gorgonians for the Nouméa museum and whilst one of these was on his dissection table he happened to notice a pair of tiny seahorses. The next year they were officially named by Whitley as Bargibant's pygmy seahorse. Other species live on soft corals or are free-ranging among seagrasses and algae.
