The baby sand tiger shark born in March is now on display! (Updated 5/14)
"Aqua World Ibaraki Oarai Aquarium, which is the aquarium with the largest number of shark species in Japan, has begun public exhibition of a baby grey shark (individual number No. 2025), a type of shark, that was born at the aquarium on Saturday, March 3, 15.

After the baby sand tiger shark was born, its health was monitored in a tank in the back yard, but since it was confirmed to be growing well, including eating food on its own, it was put on display in the "Shark Sea 2" tank. The exhibition tank also displays other sharks, such as scalloped hammerhead sharks and great nurse sharks, which are about 5m in length like the current baby sharks, and visitors can watch them swimming together. A baby birth commemorative booth will be set up near the exhibition tank from May 15th, featuring stuffed toys that allow visitors to experience the weight of the baby shark at birth.

The baby was temporarily unable to swim well due to a lack of buoyancy, but the keepers, using their experience, were able to inject air into its stomach, which helped it recover and it began to swim energetically again. This is the first case in the world where a newborn sand tiger shark has been given air injections and has recovered. The baby was also nervous, reacting sensitively to lighting, but by blocking out the surrounding light and taking other measures, the baby was gradually able to get used to its new environment.

Please keep a warm eye on this baby fish, who has overcome these hardships and is now making its healthy debut in the display tank, as it continues to grow.
