Only the fiercest hunters and most ingenious adapters survive Mexico's Baja Peninsula, where years may pass without a drop of rain. Towering above them all is the ten-ton giant cactus, the cardon, centerpiece of this community of strange and wonderful life-forms. From the deadly scorpions lurking in the sand to the lowly cactus mouse making a home in the thorns, each creature has specially adapted to this harsh place. Baja's rhythms of life also unfold in the neighboring Sea of Cortes, where manta rays and sea turtles glide past islands that are splendidly isolated from the mainland. Join National Geographic as we unlock the key to survival in this alien Mexican landscape.
