Sharks such as bull sharks, tiger sharks, silvertip sharks, and silky sharks are bred in the shark research lab tank. Some bull sharks kept in aquariums have lived for more than 45 years as of 2024. [19] The lab also displays many skeletal and fetal specimens of sharks. [57] In 2016, the aquarium showed an attempt to raise an adult great white ...
