The Pontoh's Pygmy Seahorse - Hippocampus pontohi is less than 2 cm in length, including the tail. They are most often seen in pairs or small groups in clumps of the calcareous alga, Halimeda and on the hydroid Aglaephenia cupressina. They are often found where Halimeda grows out of reef walls. Divers report them on many types of seagrass and algae, moving frequently to different hitching spots
Both Hippocampus severnsi and Hippocampus pontohi were described in the year 2008 but subsequently, there were doubts if they are actually both the same species. Am not sure if subsequently, there were further studies which should includes DNA to verify that.
