People are the biggest threats to manatees—they have no natural predators. In 2013, we have seen the most deadly year for manatees since death records have been tracked, with over 750 deaths by November 1, 2013. Challenges that manatees face include:

  • Collisions with boats
  • Loss of warmwater habitat
  • Harassment by humans
  • Flood gates and canal locks
  • Red tide
