Physical Description

 
sexual dimorphism
  • sexual dimorphism
    Sexual dimorphism is a phenotypic difference between males and females of the same species. The prototypical example is for differences in characteristics of reproductive organs. Other possible examples are for secondary sex characteristics, body size and morphology, ornamentation and behavior.

integument
  • integument
    integument differs between males and females. Includes the size, number, distribution or shape of cilia, scales, spines, hooks, bristles, feathers, hair, horns and teeth. Although not integmental structures, the antlers of mammals are included in this category because they are analogous in function to the sexually-selected horns and spines of other animals.
