💡 Interesting Facts
1
Mexico is a global hotspot for Bolitoglossa salamanders with dozens of endemic species found nowhere else on Earth; the Sierra Madre del Sur and Chiapas highlands have some of the highest salamander diversity on the planet.
2
Bolitoglossa salamanders breathe entirely through their skin and mouth lining — they have no lungs — making them extremely sensitive to air pollution, skin-contact pesticides, and desiccation.
