Pontohi pygmy seahorse amongst hydroid colony. Pontohi pygmy seahorses (Hippocampus pontohi) have only recently been described (as of 2010). They were discovered by an Indonesian dive guide in Sulawesi. Rather than living on sea fans like other species of pygmy seahorse, these minute fish prefer mixed substrates of hydroids and encrusting algae, often in overhangs on current swept rocks. Photographed in Bunaken Marine Park, Sulawesi, Indonesia.
