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.

Many aquatic animals live in a well defined area – sessile (immobile) animals obviously remain where they set up camp (a rock, a reef, a boat, another animal), but even many mobile animals stay close to home. Many fish live in or near coral reefs and do not, or cannot, swim long distances to new homes. Others are bound by adaptation to types of water environments – some live only on or near the sea floor and have to stay at the depths they are adapted to to avoid pressure changes that would kill them, for instance. Others require caves or other shelter to hide in or breed in and so defend their specific home quite aggressively.
Migratory animals like some whales may return to a similar area every year, just like birds and migratory insects do. The areas are places where their preferred food source is abundant.and conditions suit their needs (water temp, etc) so they will only find a new territory if food sources are depleted or the area becomes environmentally unsuitable (which is a major cause of food depletion).
