Kamogawa Sea World (Kamogawa-city, Chiba; Director: Hiroshi Katsumata), a key property of GRANVISTA Hotels & Resorts Co., Ltd. (Head office: Chiyoda-ku, Tokyo; President: Sadanori Suda), announces the hatching of a king penguin chick in September 2018 is conceived as a result of artificial insemination using collected semen. It is the first successful artificial insemination of king penguin in the world.
Genetic analysis of the chick was used to prove the success of the procedure. It is a scientific breakthrough which will help improve the breeding success of this important penguin species throughout the world. This scientific advancement of penguin artificial insemination and semen collection technology are outcomes in collaboration with Dr. Todd Robeck and colleagues from the SeaWorld and Busch Gardens Species Preservation Laboratory.
The chick was initially being fed by its parents and grew as big as an adult king penguin. It is also being conditioned to be hand-fed by keepers and gets about 1kg of fish daily. It will be considered to be independent after the dark colored juvenile feather molts into the adult feather.
*Please note that the exhibits may be canceled due to animal health or other factors.
Also note that more details will be released after Dr. Robeck, his team and our staff publish their thesis.
1. Demonstrated that king penguin semen which has been manually collected, and extended in media for temporary holding can result in offspring.
2. Zoological penguin populations are educational ambassadors for penguin conservation issues in the wild.
3. The techniques and knowledge gained from this advancement has the potential to be applied to other bird species, including endangered species in the wild.

King penguin (Aptenodytes patagonicus) is the second largest species of penguin, smaller, but somewhat similar in appearance to the emperor penguin. King penguins breed on subantarctic islands between 45 and 55°S, at the northern reaches of Antarctica. Instead of building nests, parents take turns to incubate their egg on their feet.
IUCN red list category and criteria: Least Concern (LC)
