Photographed on May 5 "Shirowani" juvenile (individual number: No.10)

Juvenile sand tiger sharks (individual number: No. 10) were unable to adjust their buoyancy immediately after birth, causing them to sink to the bottom of the tank and disturbed swimming. I've been taking care of it by the keeper.On the 11th day after birth, he began to eat food and gradually stabilized. I found an individual submerged in the water and confirmed its death.

It is the second time at the museum and the second time in Japan since the juvenile sand tiger shark was born on May 2023, 5 in the "Shark Sea 7" tank, and on June 2021, 6. breeding success.In addition, the successful breeding of the same parent individual twice is a remarkable achievement for the first time in Japan.


We would like to express our sincere gratitude to everyone who has supported us so far.

At Aqua World Ibaraki Prefecture Oarai Aquarium, we will continue to work on breeding gray sharks and sharks, and will continue to take on the challenge of conveying the appeal of sharks and other creatures to as many people as possible.
