While it fits into the broader genre of fiction, it also possesses elements of:
* Social Realism: The story explores the harsh realities of poverty and the struggles of Mexican-American fishermen in Baja California.
* Tragedy: The novel follows Kino's journey from hope and ambition to despair and loss.
* Folklore/Myth: The discovery of the pearl is presented as a transformative event that evokes both awe and fear, drawing parallels with traditional stories about the power and dangers of wealth.
