Known as the "Peter Pan" of animals, the Mexican axolotl is a unique type of salamander that spends its entire life in its larval form and is found only in Mexico's Lake Xochimilco. It lives underwater, and its odd appearance and ability to regenerate body parts make it a popular animal kept in labs and schools. Fewer than 1,200 Mexican axolotls remain today because the lake is drained to provide water for nearby Mexico City, and it has suffered from the introduction of invasive species like carp and tilapia, which eat the axolotls. Roasted axolotl is also considered a delicacy in Mexico. In June, writer DBC Pierre collaborated with musicians to create "An Axolotl Odssey," a symphony in honor of the critically endangered animal.
