The jungles of Mexico are home to three species of monkeys: spider, howler, and black howler. Intelligent and endearing, these creatures are prime targets for the pet trade. They have been so hunted, in fact, that today all three are in danger of extinction.
Experts estimate that for every monkey sold, three die during transportation and distribution. In an effort to protect these creatures, the Mexican government has prohibited their capture or trade.
As you wander through the ruins of Calakmul  or Cobá , keep your ears perked and your eyes peeled. You’re sure to see — or, at least, hear — a few tropical monkeys. A tip: Spider and howler monkeys are most active at sunrise and sundown; if possible, consider waking early or staying late to increase your chances of spotting a few.
