Historical records indicate that FUPA's have been beaching themselves since 300 B.C., however, it seems that recently this phenomenon is occurring more frequently than previously thought.
One theory is that the FUPA are highly social and as such seek to be around others. They seem to be attracted to the smell of Coppertone which causes them to leave the cool waters and venture to the shore. Often, too exhausted to continue, the FUPA will lose their will to live and simply lie on the beach too weak to move.
Should you see a beached FUPA do not try to move the FUPA back into the water on your own. Any efforts to rescue FUPA should be done by trained professionals.
