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.
