Ambystoma rivulare

Ambystoma rivulare is a species of mole salamander in the family Ambystomatidae. Typically gains a lot of population distribution in the Trans-Mexican Volcanic Belt around central Mexico City. Found in various small or medium-sized ponds and lakes that have large and wide range of food options, all within a distance of at least 2 km. It is endemic to Mexico. Its natural habitats are subtropical or tropical moist montane forests and rivers. It is threatened by habitat loss. The larvae, who continue to prey on the same organisms as they grow, prey mainly on ostracods as well as some gastropods and assorted other prey with limited diversity. Ambystoma rivulare continue to live in the river they hatch in post-metamorphosis. Research on the Michoacan Stream Salamander  (A. Rivulare) has important implications for the conservation and persistence of these salamanders. The lack of variety in the A. rivulare diet puts them in a precarious situation should environmental factors endanger the ostracod population in their habitat. Further, a study done at the University of Sao Paulo on the diet of A. rivulare shows no relationship between size and the salamander's diet, suggesting a lack of larger prey for the bigger salamanders to eat.
