Juvenile Pinnate Batfish - Platax pinnatus, still almost all black in colour with borders of orange. This is supposedly a mimicry of 'Flatworms' which are poisonous, thus a way for their protection when small in size. As they get's bigger, they will takes in more silverfish colour, the fins becoming shorter and the orange border will fades eventually.

''Platax pinnatus'', also known as the pinnate batfish, dusky batfish, shaded batfish, or red-faced batfish is a fish from the western Pacific that occasionally is kept in marine aquariums.

The pinnate batfish (Platax pinnatus) lives in the Indo-West Pacific near coral reefs where they feed on algae, jellyfish, and zooplankton. Juveniles are breathtakingly beautiful with black bodies that are outlined in vibrant orange. But, as they mature, they lose their juvenile features and become a dull silver color. They are shy fish that deserve to live their lives in the wild, especially since they do not do well in captivity. Some may live for a few months, but 90% die within hours of being captured. But, thanks to gorgeous photos like this one, we can easily admire these magnificent fish in their natural habitat. {Spotted in Philippines by JungleDragon moderator, Albert Kang} #JungleDragon #Juvenilepinnatebatfish #Batfish #Plataxpinnatus Posted 5 years ago
