About the aquarium animal trainer ~ ~

You don't need to take any certificate, whether you are a sea lion trainer or a dolphin trainer, you need to be very good at water, because some actions require people and animals to perform underwater, such as dolphins flying people and saving people. Dolphins need to lift the trainer from the water, and it is very difficult if they can't dive. There is also a general need to learn aquaculture or animal husbandry. If you can't, you might as well send a resume to the aquarium, maybe you will be hired.
