The Pygmy Seahorse is as small as a paper clip. The babies grow tubercles and they can change colour so that they camouflage.
Scientists went to the Philippines to get Pygmy Seahorses to take them back to San Francisco because they want to find out if Pygmy Seahorses change colour.
When the baby Pygmy Seahorse came out of the males pouch they changed colour. They camouflage with the coral.
