Aqua Planet Jeju which in South Korea has three Asian short clawed otter(ASCO). I visited there and watched their behabior and life.
Never imagined that I could go Korean Otter Research Center ( Hwacheon , South Korea ). There're 11 otters on exhibit (as of May 17th ).
I visited South Korea for four days. Needles to say, the purpose is to watch otters!!
