The pygmy seahorse, also known as Bargibanti’s seahorse, (Hippocampus bargibanti) is a seahorse of the family Syngnathidae found in the western central Pacific Ocean. It is tiny, usually less than 2 centimetres in size and lives exclusively on fan corals.
There are two known colour variations: grey with red tubercles, and yellow with orange tubercles. Because of its camouflage, the species wasn’t discovered until its host gorgonian was being examined in a laboratory. Scientists believe other, similar, species remain to be found.
