Because some animals can't survive on land, so they have to live in water and they have gills so they have to have water!
Some animals, such as dolphins and whales, actually DID live on land at one time, and REGRESSED or RETREATED to the sea. No one knows why. Perhaps it was easier to survive in the seas' waters instead of upon the earth, where it may been very volcanic and warm at that time.
In other instances, perhaps jellyfish could not adapt to land because foraging in the sea was easier for them.
Many questions remain unanswered.

What is the connection between the types of native animals on the Galapagos Island and their ability to cross the open ocean?
The native animals of the Galapagos Islands, such as the Galapagos finches and sea turtles, showcase remarkable adaptations that enable them to cross open ocean distances. Many of these species have evolved traits like lightweight bodies, efficient navigation abilities, and specialized behaviors to facilitate long-distance travel. Ocean currents and winds assist in their dispersal, allowing them to reach these isolated islands from the mainland. This connection highlights the interplay between evolution and environmental factors in shaping the biodiversity of the Galapagos.
