The sea otters who live south of Tokyo got more of their special treats as they look to celebrate Valentine's Day.

For male sea otter, Yutan, living at the Yokohama Hakkeijima Sea Paradise it's become a chance to show visitors how much he likes to show off.

Yutan has been fed every day by breeding engineer Chizuko Shinozaki and when asked about visitor's reactions so far, she says, it has been good.

Sea Otters are the only aquarium residents to get their heart shaped treat before Valentines day.
