National Geographic-Snake Wranglers

Cozumel Island is facing a biological disaster due to the introduction of an alien species:
the boa constrictor. Where did these boas come from? How much damage are they doing?
What can be done to stop their onslaught? These are questions that constrictor expert, Jesus Rivas,
will try to answer by teaming up with local scientists to assess the magnitude of the problem.
Alien species, like the boa, can exterminate native species by competing with them, preying upon
them or destroying their habitat. These effects are magnified in an island ecosystem. Jesus and the team
are on the case, looking for a solution before the problem gets any worse.
