Pygmy seahorses are very very small (max 1 cm) and know to disguise themselves pretty well. They either live on seafans, soft corals or marine plants. They have the same colour and structure as the home they live in (on) and do not always sit upright. They tend to dangle around or ly flat, making them blending in more.
They were first discovered in a lab, where a scientist checked out some Gorgonian sea fans and just happened to find one of them. And ever since new species have een discovered.
