Morphotype, often abbreviated to morph*, is a term used to describe an infrasubspecific group of animals distinguishable from other animals of the same species or subspecies on the basis of morphologic characters. For example, the cannibalistic morph of Ambystoma mavortium mavortium has a wider, flatter head, with an extra row of vomerine teeth which are often recurved.
