The Amazing Pygmy Seahorse

The seahorse has been known to us for thousands of years: the ancient Romans created beautiful mosaics celebrating their shape and grace. Yet a number of species escaped our attention until the 1970s - and then it took till the 21st century to name six of the seven previously hidden kinds.
Why did they elude us for so long? Well, they are tiny. Yet it is their amazing camouflage which really allowed them to remain concealed for so long.
