In addition, the past eight surveys of tagging whale sharks have revealed that they can migrate to the Philippines and dive to a depth of .  The aquarium has been breeding and studying Giant Devil Rays since 2008. "OBIC" devil rays were trained for health management for transportation to the Pacific Tank, and a large 8-meter-diameter tank was set up on the deck of the ship, The giant devil rays were transported over a long distance from Kochi Prefecture to Osaka under conditions that allowed them to swim freely. At the aquarium, giant devil rays became pregnant in 2022. It was the first time in the world that a giant devil ray was conceived in captivity. After the pregnancy was discovered, regular ultrasound examinations were used to check the growth of the fetus and to record changes in the mother's abdomen bulge and behavior. In addition, to protect the pups after birth, a partition net was set up in the tank in preparation for the birth. Pups were born on the morning of May 16, and although the birth was celebrated with great fanfare, the pups swam unsteadily and weakly, and died at 16:18. Based on the results of the pathological autopsy and blood tests, the cause of death was considered to be due to an imbalance of blood due to physical exhaustion from not being able to swim. In addition, since the opening of the Osaka Aquarium, it has succeeded in breeding

. Peter Chermayeff also built the Lisbon Oceanarium in Portugual and other buildings. The three color schemes that characterise the exterior of the building mimic the union of earth, water, and fire. The fish mural on the exterior wall was painted by Serge Chermayeff, an English designer living in the United States, and the entire building was designed by his son, Peter, who headed the Cambridge Seven Associates Environmental Development Institute. Visitors first take an escalator up to the 8th floor, and then walk down a corridor to the 4th floor. The first three floors are machine rooms containing filtration equipment and are not open to the public. Unlike the usual method of filling and unloading the tank (filling from the water surface and unloading from the bottom), the water is filled from the bottom of the tank and unloaded from the top. This is to make it easier to collect leftover food and bodily waste floating in the tank by creating a water flow from the bottom to the top, and to increase the clarity of the water. Oxygen is supplied by creating artificial waterfalls. Most of the waterfalls are located behind the tanks, but some are visible to visitors for production. The tanks used in the aquarium are made of of

Kaminuma, who was a member of the name selection committee among the common candidates starting from Marine, chose Kaiyukan, which had only one vote, and said, "It is better to make it an impactful "Kaiyukan'". Emiko Kaminuma further said, "There is no impact with a mundane name that starts with Marine. If it is expressed in three kanji characters, the meaning will be easier to understand, and it will have an easy-to-understand impact like (夢工場)." As a result, it does not have a name starting with Marine, which had a large number of votes, but was named Kaiyukan.
