A mother manatee (pictured above) swims up to a cave diver in a flooded cave in Quintana Roo, Mexico's Yucatan Peninsula. Klaus ThiemannThey captured amazing photos of these endangered mammals living in unique, unexplored habitats. “Of course I think she's looking at me,” Tyman says. “But in reality, she's probably seeing what's on camera.”

Carved into the limestone by flowing water, this cave system is thought to be up to 16,000 kilometers long and connects coastal and inland cenotes, freshwater-filled sinkholes created when cave roofs collapse. is. Timan and his fellow divers have been exploring this system (pictured above) to photograph manatees, which, unlike humans, can easily navigate passages.
Although manatees have likely lived in the area for generations, it is estimated that fewer than 250 manatees exist in the Mexican Caribbean, Tiemann said. Timan is concerned that nearby construction projects are endangering aquatic species in the area. A new railway line will further develop this popular tourist destination (pictured above). Construction can impede the flow of water through the system, starving it of oxygen and trapping manatees. Wastewater from surface runoff and sewage systems degrades the water quality of local aquifers.
Although the coastal area is protected as a manatee sanctuary, it does not extend as far inland as the manatees were photographed. So while the discovery of manatees in a relatively pristine cave system is good news, these habitats may not remain pristine for very long.
