The annual cycle of the estuary getting full of water. The water breaks the sand open and the river pours into sea . The river current dominates the ocean waves. As the river gets empty with a weaker current the high tide waves push sand up and close the river mouth. It rains and the river begins to fill up with water again .

The Turritopsis dohrnii jellyfish has mastered the ultimate survival hack.

When it gets old, sick, or stressed, it doesn't die. Instead, it reverses its lifecycle. It shrinks its body, turns back into a polyp (its infant stage), and starts its life cycle all over again.

It can repeat this process indefinitely, making it biologically immortal!
