3 Years in a row! This year too, a baby Manta was born in the Okinawa Churaumi Aquarium (Kuroshio Sea)
2009,9,29 category：Tank info
Now, we at Okinawa Churaumi Aquarium would like to inform you of the successful birth in captivity of a baby manta for the third year in a row (2007, 2008 and 2009).
Inhabiting the tropical and sub-tropical seas of the world, this is the world’s largest ray, thought to reach over 6.7 m disk (body) width. Although large, it is docile, feeding by filtering the seawater for plankton, mostly krill (shrimp relatives). Kept at Okinawa Churaumi Aquarium successfully since 1988, the world’s first manta birth in captivity was recorded here in June, 2007, but unfortunately, that pup did not survive. Last year in June for the second time in the world, we had a successful manta birth in captivity, and now the manta pup is on display in the Kuroshio Sea Tank. We now announce the third birth of a manta ray in captivity. 。
Date of Birth: June 24, 2009 (Wednesday) 16:58
Place of Birth: Okinawa Churaumi Aquarium (Kuroshio Sea) Big Tank, 35 m X 27 m X 10 m Deep, Volume 7,500 cu. m.
Individual Born: One female, Disk Width 192 cm, weight 70 kg
Mother Manta: Captured August 3, 1998, in a Yomitan Village Set-net Time in Captivity 10 years, 10 months*
Father Manta: Captured May 25, 1992, in a Kanna (Ginoza Village) Set-net Time in Captivity 17 years, 1 month*\
*(as of June 2009)
The mother which gave birth this year copulated last year on June 17, so gestation time was 372 days. This time, the birth occurred during open hours of the Aquarium, and the moment of birth could be observed by numerous Aquarium visitors. The anxiously anticipated Baby Manta was greeted with shouts of joy! Immediately after her birth, Aquarium staff removed her from the tank, and transferred her to a sea pen 2 km south of the Aquarium, where she is under continuous study and observation. Very little is known about this species, so with this birth, we hope to continue contribute to the knowledge of its ecology and natural history.
