Abstract

Describes for the first time the existence of an Ambystoma tigrinum tigrinum larval morph characterized by fast growth rates and early metamorphosis and triggered by cannibalism. This new morph does not have the anatomical specializations of true A. tigrinum cannibal morphs (enlarged vomerine teeth and a wider head). Functionally, however, this new morph and true cannibal morphs achieve the same end; high growth rates and early metamorphosis may facilitate survival in individuals inhabiting temporary and unpredictable wetlands. -from Authors
