We are exhibiting a baby sand tiger shark born in March 2025.
Aqua World Ibaraki Oarai Aquarium is currently exhibiting a baby grey nurse shark (individual number 11), a type of shark, that was born at the aquarium on Saturday, March 15, 2025.
The current exhibit, "Shark Sea 2," displays sharks such as scalloped hammerhead sharks and great nurse sharks, which are about 1 to 2 meters in length, the same size as today's children, and you can watch them swimming together.

When No. 11 was born, he was unable to swim well due to a lack of strength, but the keepers, using their experience, were able to inject air into his stomach, which helped him recover and he is now swimming energetically. This is the first case in the world where a newborn sand shark has been given air injections and recovered. He also showed signs of being nervous, such as being hypersensitive to light, but by blocking out the surrounding light and taking other measures, we were able to gradually get him used to his new environment.
Please keep a warm eye on them as they overcome their hardships and swim energetically in the exhibition tank, and watch them grow in the future.

"Sand Shark"Since they only breed once every two years, this breeding season marks their third consecutive successful breeding season.By the same individualThis is the world's first feat of three consecutive pregnancies and reproduction..
This world's first successful breeding success of three consecutive seasons is proof that many years of research have made it possible to create an environment suitable for the breeding of grey nurse sharks, and we believe this will also make a significant contribution to the conservation of this species, which is classified as endangered.
