We have just recently had our 4th successful manta ray (Manta alfredi) birth in captivity at Okinawa Churaumi Aquarium.



Living in tropical and surrounding seas of the world, this is the largest-known species of ray , with a body diameter (disc width) estimated to reach over 6.7 m across. Commonly known as the Manta, it feeds on small fish, plankton, and other small organisms. We first began keeping Mantas in our tank in 1988, and for the first time in the world, we were successful in keeping a manta ray for a long time. In June, 2007, we had our first manta birth, and every year for the last four years in succession we have had a successful birth! This year’s birth is our fourth, and also the fourth birth in captivity in the world. The new baby Manta’s big brother and big sister, born in 2008 and 2009, are now on display together in the Kuroshio Sea Tank.

Date of Birth: June 26, 2010 7:21PM
Place of Birth: Okinawa Churaumi Aquarium (Kuroshio Sea Tank)
Sex: Female
Birth Size: Body width (Disc width): 182 cm, weight 66 kg
Mother Manta: Captured by set-net off Yomitan, Okinawa, August 3, 1998.
Being kept as of June 26 for 11 years and 10 months.
Father Manta: Captured by set-net off Kanna (Ginoza), Okinawa, May 25, 1992.
Being kept as of June 26 for 18 years and one month.
*June, 2010 The Present

The mother Manta who gave birth last year was confirmed to have mated again on June 24th, so the term of pregnancy in mantas is about one year.

This year, just as last year, the birth occurred during open hours at our Aquarium, so our visitors gave the mother and baby a big round of applause and shouts of welcome!
Immediately after the baby Manta was born, the keepers lifted her out of the tank and transferred her to a sea pen, where she will be taken care of and continuously observed .This birth is an obviously important step on our way to understanding about the behavior and ecology of mantas. There are still mysteries to solve about the ecology of this species, so this research will provide us very important data.
