This is true particularly in mammals with polygynous mating system, but there are clear limits to either body size (for a number of biological, biomechanical, and ecological constraints) and in behaviour disposition.

A tiger killed on the Sumbar River in Kopet Dag in January 1954 had a greatest skull length of 385 mm (15.2 in), which is considerably more than the known maximum for this population and slightly exceeds that of most Siberian tigers.
