Release Of Ajolotes In Xochimilco, Mexico City

View of salamanders inside a fish tank at the Centro Ecoturístico Chinampero Michmani in Xochimilco, Mexico City. The Mexican axolotl or ajolote, Ambystoma mexicanum, is a salamander with the unusual characteristic of retaining its larval features as an adult. This condition, known as neoteny, means that it retains its tadpole-like dorsal fin - which runs almost the entire length of its body - and its external gills, which protrude from the back of its broad, feathery head.
