The pygmy seahorse and the dwarf seahorse are both among the tiniest seahorse species in the world, but they live in different oceans and rely on different strategies, one on precise coral camouflage, the other on anchoring tightly to seagrass.

Pygmy Seahorse vs Dwarf Seahorse: common questions
Where does the pygmy seahorse live compared to the dwarf seahorse?
The pygmy seahorse lives on a specific type of gorgonian sea fan coral in the western Pacific, while the dwarf seahorse instead anchors itself to seagrass blades in the Gulf of Mexico and parts of the southeastern United States.
Which is more at risk, the pygmy seahorse or the dwarf seahorse?
The dwarf seahorse, which is listed as Vulnerable due to declining seagrass habitat, while the pygmy seahorse has not been formally evaluated for conservation status.
How was the pygmy seahorse first discovered?
It was found by accident after a researcher noticed a specimen still attached to a piece of host coral that had been collected for an unrelated purpose, a discovery story the dwarf seahorse does not share.
