This is a traditional proverb (refrán) with its roots in popular wisdom. Its origin is anonymous and it has been passed down orally for generations. It reflects a practical, cautionary worldview, likely born from coastal communities where observing nature directly translated into life lessons.

This is one of the most common proverbs in the entire Spanish-speaking world. It's used by everyone, from grandparents teaching a life lesson to colleagues in a meeting, to stress the importance of vigilance and proactivity. It perfectly encapsulates the cultural value placed on being 'listo' or 'despierto' (clever, sharp, or 'awake').

The proverb's power comes from its simple, vivid metaphor. The 'camarón' (shrimp) represents any person, especially one who is small or vulnerable. 'Dormirse' (to fall asleep) is a metaphor for being inattentive, lazy, or complacent. The 'corriente' (current) symbolizes the unstoppable flow of time, competition, or life's circumstances that will inevitably move on without you.
