A full-grown pygmy seahorse is maller than a grape in size. Its camouflage makes it almost invisible in coral.


Pygmy seahorses are remarkably small critters, generally maxing out around 2 cm (0.8 inches) long.


The first species of pygmy seahorse ever discovered was the Bargibanti pygmy seahorse (Hippocampus bargibanti) in 1969.


The knobs on its skin – called tubercles – help it blend in with the texture of the branches.


Sometimes defense is the best offense. Discover how pygmy seahorses are able to cunningly camouflage themselves amidst coral reefs in this educational short from MacGillivray Freeman Films' IMAX documentary “Journey to the South Pacific.”  Learn more at
