According to wiki:
"Although called the eleven-armed sea star there can be any number up to 14, but 11 is the norm. They are often found with arms of varying lengths, regenerating to their original length. It can reproduce itself by fissiparity (self division), being capable of regenerating even one arm into a whole new body, but only if the arm includes part of the central disc"
It's a quite amazing species :)
