Thank you for all the moving moments! Pata the sea otter has passed away at the age of 18

Thank you for all the touching moments, Pata. And thank you to everyone who loved Pata so much. On Tuesday, October 10, 2017, at 4:00 a.m., Pata, a sea otter born at Kaiyukan, passed away. He was 21 years old. Pata was the oldest sea otter born at an aquarium in Japan, and was a very long-lived sea otter, considering that the life expectancy of sea otters is generally said to be 15 to 20 years. Pata is a female sea otter born at Kaiyukan on June 28, 1996. She has lived at Kaiyukan since she was born, and as a baby, she became a hot topic for the adorable sight of her floating on her mother's stomach as she swam on the surface of the water. She was mischievous and mischievous. Photos of her cute appearance were often featured on the web, and every year on her birthday on June 28, she received birthday cards from customers, and applications to participate in her birthday party events flooded in. Pata had many fans all over Japan, which is unique to her. Pata was the sea otter that was able to do the most through training, such as shaking hands on land, opening his mouth wide, and stepping on the scale by himself. Because he was able to do such a variety of training well, we were able to manage his health by checking his injuries, weight, and physical condition for many years, and he lived a long and healthy life. Pata's health condition changed around Tuesday, October 3, 2017, and we continued to care for him 24 hours a day in the back yard from Sunday, October 8, but he passed away due to old age. Please note that we are not currently exhibiting sea otters at Kaiyukan. ◆From the person in charge "Pata was born at Kaiyukan and we have been watching him for 21 years. He had a unique personality of being particularly "selfish" among sea otters, and he caused us a lot of trouble. He was small among sea otters and did not seem to have a strong body, but before we knew it, he had become the oldest aquarium-born otter in Japan. He really did his best. Pata has been living alone for the past few years, so the aquarium keeper visited him as often as possible, giving him stimulation in his life and watching over him to ensure he lived a healthy life. In those days, all the aquarium keeper, including myself, learned a lot from Pata. We are grateful. We feel very sad and lonely now, but we want to tell Pata, "Thank you so much!" " (Manager of the Marine Mammal Environment Exhibition Team at Kaiyukan Animal Care and Exhibition Department, Chimoto (in charge of marine mammals since Pata's birth) ◆ To everyone who loved Pata Thank you very much to everyone who has cherished Pata the sea otter. With his many charms, Pata has taught us the wonder and wonder of sea otters and marine life, and Kaiyukan is grateful to him. Kaiyukan plans to hold a venue to express gratitude to Pata. We are considering whether we can accept the feelings of all those who love Pata at that time, so please wait. ◆ About Pata the sea otter Nickname: Pata Sex: Female Age: 21 years old (as of October 10, 2017) Birthday: June 28, 1996 (born at Kaiyukan) Special Characteristics: He has a cute face, but is quite moody. He often troubles the aquarium keeper. He likes ice and crabs that he gets as snacks. However, depending on his mood, he throws them away without eating them, which makes the aquarium keeper cry. However, even that appearance is charming, and for Kaiyukan years, aquarium keeper at Kaiyukan. With that charm, he has widely conveyed to us the wonderfulness and wonder of the creature called "sea otter". ◆ About Kaiyukan and Kaiyukan otters Although there will be no sea otters at Kaiyukan, we would like to use the experience and knowledge we have gained from raising them for 27 years since the aquarium opened to help with sea otter conservation and conservation activities. We will continue to conduct research on the ecology of sea otters and work to help protect and conserve sea otters living in the wild.

A baby Southern rockhopper penguin was born!

You can see the adorable baby and the heartwarming care of the baby in the "Falkland Islands"tank in the new experience area. On the morning of Wednesday, June 7, 2017, a baby Southern rockhopper penguin was born. In the "Falkland Islands"tank, which is open to the public, you can see the adorable baby and the heartwarming care of the baby. The parent birds are currently raising the baby diligently. The baby hides under the parent bird's belly, but you can see it pop out and chirp when the parent bird moves. The Southern rockhopper penguin baby was born from a parent bird that was artificially inseminated. Last year, Kaiyukan was the first in the world to successfully artificially inseminate a Southern rockhopper penguin, but this time, as a further development, artificial insemination was performed using frozen sperm. It will be determined in about one month by DNA testing whether the baby was artificially inseminated. If artificial insemination is confirmed, it will be the world's first successful artificial insemination using frozen sperm in Southern rockhopper penguin.

Four new species of shrimp and crabs will be exhibited in the "Japan Deep" tank on the 4th floor of Kaiyukan ! Kaiyukan is conducting research on deep-sea creatures around Cape Muroto in collaboration with the Kochi Prefectural Deep Sea Water Research Institute.

The Institute announced this as a new species. This is the first time it has been exhibited at a Japanese aquarium. ◆ Paromola Japanese deepwater carrier It can fold its fifth leg backwards, and uses this leg to hide by carrying sponges and scales on its back. ◆Okinosuji shrimp Scientific name: Plesionika narval A member of the genus Plesionidae that lives at depths of 200 to 300 meters. From spring to early summer, they can be found less than 30 meters shallower, and since they form large schools, it is thought that they migrate to shallow waters to breed. ◆Tsunoiwaraebi Scientific name: Eumunida dofleini Although it looks like a crab, it is a shrimp of the Eumunidae family that lives in deep temperate seas. *The detailed ecology of the creatures on display this time is not yet known, so the display may end without notice.
