A few weeks ago, I mentioned that Google had teamed up with Catlin Seaview Survey and produced the first ever underwater street view for select coral reefs around the Great Barrier Reef, Hawaii, and the Philippines. During this survey, the mapping team found something interesting: a tiny Denise’s pygmy seahorse (Hippocampus denise). Denise’s pygmy seahorse measures only 5/8 inches long (1.5 cm) and lives a solitary life on their host gorgonians. This particular seahorse was found at Holmes Reef in the Coral Sea, off the coast of Queensland, beyond the Great Barrier Reef, at a depth of 302 feet (92 metres). It is also on the IUCN Red List of Threatened Species. This is the first ever reported sighting of this seahorse in this area.
