The panda uses many defense mechanisms including biting, clawing, and their size to escape and fight predators. Their size helps before they start fighting. A panda is huge and this will usually stop the fight. However, biting and clawing will happen when the panda has been cornered and has no other choice. At this time, the adult panda can be very vicious and can leave a bloody mark. On the contrary, pandas can not fight against humans. That is why humans are pandas greatest enemies. Therefore, pandas can fight against all predators but humans.
