We found this starfish with four arms about 100
kilometres south of Broome on the north-west coast of Australia. Is it
unusual? How did it evolve? How many or how few arms can starfish have?

I took this picture whilst travelling in the Longsheng area of Southern China, towards the end of last October. Can anyone please explain what these creatures are, and what they are doing?
