A recent three week mission to Indonesia's coastal waters has revealed at least 50 new animal and plant species living there.  Over 100 hours of video and some 100,000 photos were taken by a robot submarine's HD equipment.  Scientists were amazed to see that crinioids, or sea lillies, which were abundant in prehistoric seas but very rare today, grow in large numbers and varieties here.  Among the oddities spotted durig the video exploration sea spiders the size of dinner plates, a purple colored, short tentacled octopus, and what seems to be a carnivorous sponge.  Researchers also got good photos of a strange fish that walks on the sea floor using its fins that are shaped like arms and hands.
