Ocean currents and swells are also how ancient Polynesians navigated the ocean so precisely over such huge distances. They developed the ability to read them like maps. Unfortunately, these skills are almost totally extinct. I believe there's only one Hawaiian "master navigator" in the old ways left alive. That intelligent animals could also survive by using this information is not at all unbelievable. Very cool and interesting to think about.
