crypsis
n.— «The correlation between body weight and the presence of horns in females may be a consequence of the relation between body weight and antipredator behavior in antelopes: smaller species rely on crypsis or flight while large species often show direct defense against predators.» —“Sexual dimorphism: the horns of African antelopes” by Craig Packer Science Sept. 16, 1983.
