Pygmy Seahorse is absolutely tiny, and t a fully grown individual is no larger than the size of a human fingernail ! Beyond their small stature, Pygmy Seahorses are able to almost perfectly camouflage amongst the branches of soft Gorgonian corals - which are also animals (not plants) - imitating the texture and colouration of their hosts to perfection. If the Gorgonian coral contained slightly more red or yellow hues, for example, the Pygmy Seahorse would be dressed to match.
