Land or air animals usually have a home or a region where they live like next to bird nests, next to river, etc. Does the same happen for water animals? Like when a whale migrate, when they go back, they go to the same region or they just find another cold water place? Or when turtles need to deposit eggs, they always go to the same specific beach. Or just some random fish who doesn’t swim too far sleep at the same hidden place everytime.

I think this may help. I always liked the story of the shrimp that live in glass sponges. A male and female shrimp will move into the sponge and defend it from other would be tenants. Eventually they become to big to leave and live their lives eating by filter feeding. My professor had a glass sponge that was filled with a few shrimp remains and said that some cultures would give them as wedding gifts to signify living together for the rest of their lives.
