Clawless otter twins have born on April 10th,2017. I visited Ise sea paradise which has the babies, May 18th. Their eyes are not open as of then.
A young couple of clawless otters are now on exhibit at Sendai Umino-mori Aquarium. There are only 3 facilities hold and exhibit clawless otters in Japan. We can't meet them except at those precious facilities!
I went to a small aquarium, Futami Sea Paradise, in Mie prefecture. Gladly, the clawless-otter babies were born in March 17th, here at Futami.
