Cuetzalan Amphibians

Amphibians represent the transition from life from water to land, they were the first animals to come out of the water and start breathing oxygen from the air, so they have been on this planet since before the dinosaurs

All amphibians hatch from eggs and generally go through a larval stage where they breathe oxygen from the water.

Then metamorphosis occurs,
they develop lungs and become adults.

Some change their diet from herbivorous to insectivorous while others species are lifelong predators.

However, several species have developed adaptations to skip the larval stage and hatch into miniature adults from their eggs.

All amphibians have thin, permeable skin that even allows them to breathe through it.

In fact, some salamanders have lost their lungs to leave all the task of capturing oxygen from the air to the skin.

This also makes them very sensitive
to pollution, so they are excellent indicators of the quality of the environment.

In addition, their insect-based diet makes them natural pest controllers.

Mexico is the fifth country with the largest number of amphibian species in the world.

Unfortunately, more than a half of our amphibians are endangered.

Worldwide amphibians are suffering an extinction crisis comparable to that of the dinosaurs; for that reason it is urgent to take actions to protect them.
