A scientist of the Biology Institute of the National Autonomous University of Mexico (UNAM) checks zooplankton at a canal of Xochimilco in Mexico City February 13, 2014. Scientists at UNAM's Biology Institute have warned the Axolotl (Ambystoma mexicanum) or Mexican salamander, could be at risk of extinction in the wild in five to 10 years as axolotl populations were declining in 2003. But a few canals in the southern Mexico City suburb of Xochimilco, the only waterways where some axolotls may still live, are threatened by pollution caused by the city's continuous expansion and the days of the species in the wild are numbered. The axolotl is now on the endangered species list of the Convention on International Trade in Endangered Species (CITES). Picture taken February 13, 2014.
