We will be holding a special exhibition, "Dreaming of Living in the Sea - Mysterious Home for Fish and Me"!

A special exhibition "Dreaming of Living in the Sea - My Mysterious Home with Fish" will be held to introduce the "lifestyles and lifestyles" of fish! This special exhibition will display about 115 fish of 13 species with distinctive lifestyles and lifestyles, with the theme of "homes" that are familiar to both fish and humans. Other highlights include wall images that recreate "schooling fish" living in the vast ocean using a simulation program called Boids, an interactive digital installation in which schools of fish gather in response to the viewer's movements, and "aquaponics" (approx. 2.2m in diameter, 2.2m in height), a recycling-based cultivation system that grows plants and living creatures in the same system, with the theme of the Earth, which is the "home" of all living things. The space is filled with a unique worldview where elements of the sea world and the human world are mixed together, stimulating the imagination and creating "new discoveries" about the fun and charm of fish. Through this viewing experience that makes you feel as if you have stepped into the world of a picture book, we hope that you will empathize with the ingenuity and lifestyle of the fish and deepen your interest in nature. Period: Friday, March 15, 2019 to Tuesday, January 7, 2020 Time: Same as Kaiyukan business hours Location: 4th floor, Kaiyukan Entrance Building Fee: Included in Kaiyukan admission fee Exhibit species: Approximately 115 specimens of 13 species (excluding aquaponics) Diver, Razorfish, Southern mudskipper, Crocodile sea bream, Japanese giant porgy, Japanese steelhead shrimp, long-finned snakehead, angel crab, somen hermit crab, Ishida hermit Common octopus, Common octopus, sea anemone, Clown anemonefish Inquiries: Kaiyukan Information 06-6576-5501

What the Pacific white-sided dolphin sided dolphin arch left behind

Since its opening in 1990, Kaiyukan has been breeding and exhibiting dolphins in an tank that recreates the natural environment of the Tasman Sea . Arch (nickname) was the first Pacific white-sided dolphin sided dolphin to come to Kaiyukan . Not only was the facility new, but the aquarium keeper were also inexperienced, but Arch taught us everything we needed to know about breeding Pacific white-sided dolphin-sided dolphins. From 2001 to 2014, Arch gave birth a total of five times, and we learned from him the difficulty and wonder of connecting lives, from the way the fetus grew, to the moment of birth, to the way he swam close to the small and helpless baby all night long, and the deep love he has for the baby dolphin. He also left us information that can only be obtained in captivity, such as "the breeding ecology of Pacific white-sided dolphin white-sided dolphins," "behavioral analysis of baby dolphins and mother dolphins," and "collection of basic data for artificial insemination." Arch, who gave us so much information, unfortunately passed away on December 24, 2018. Through the breeding and exhibition of Pacific white-sided dolphin, we will continue to strive to convey the fascinating nature of the evolution and adaptation of marine mammals, as well as the wonder and preciousness of life, and to contribute to the preservation of species and their habitats through our research.

When fully grown, the umbrella diameter is 50cm and the weight is about 10kg, with some large individuals said to reach 80cm and 20kg. There are no tentacles on the edge of the umbrella, and each of the eight oral arms has numerous rod-shaped appendages. The umbrella is white and the oral arms are red.

A Southern rockhopper penguin has been born. If artificial insemination using frozen sperm is successful, it will be a world first.

A newborn Southern rockhopper penguin was born. If artificial insemination using frozen sperm is successful, it will be the first time in the world Three Southern rockhopper penguin chicks were born in the "Falkland Islands" tank , which is open to the public, from Wednesday, June 13 to Monday, June 18, 2018. All of the newborn Southern rockhopper penguin chicks were born from parents who had undergone artificial insemination. In 2016, Kaiyukan was the first in the world to successfully artificially inseminate this species using liquid-preserved sperm. As a further development, the parents of the chick born on Saturday, June 16 this year were artificially inseminated using frozen sperm. The success or failure of the artificial insemination will be determined in about one month through DNA testing using blood attached to the inside of the eggshell and behavioral observation of this species kept at Kaiyukan. If the artificial insemination is successful, it will be the first in the world to successfully artificially inseminate this species using frozen-preserved sperm. Currently, the parents are diligently raising their young. The chicks hide under the parent's belly, but you can see them popping out when the parent moves and chirping. Significance of artificial insemination using frozen sperm Establishing and spreading the technology of artificial insemination will improve the breeding of penguins in aquariums and zoos in Japan and abroad. Furthermore, if the technology for freezing and storing sperm can be established, frozen sperm (genes) can be stored semi-permanently, which will contribute to the preservation of the wild Southern rockhopper penguin, which is at risk of extinction. About the Southern rockhopper penguin It lives on islands around Antarctica, such as the Falkland Islands, and is a small species of penguin with a body length of about 50 cm. It got its name from the fact that it moves by hopping around the rocks. It is characterized by a yellow crest above its eyes. It builds nests from pebbles and weeds on coastal rocks, and females usually lay two eggs per breeding. It has a somewhat violent temperament among penguins. It eats small fish and krill. It is designated as an endangered species on the IUCN (International Union for Conservation of Nature) Red List. The total number of Southern rockhopper penguin kept at Kaiyukan is 18 (7 females, 11 males).
