The morphology of the noble Benitoite
(This gem is heavily based on the fictional gem "Budgerite" that was featured in the book "Steven Universe: Art and Origins". All credit goes to the creators of the show for the original concept)
Benitoites are unusual, highly specialized gems that bear many characteristics that are typical of avian species. Their "hair" is actually composed of rigid, feather-like structures, and unlike most other gem types, their legs are digitrade in structure rather than plantigrade, bearing prehensile, opposable toes that can serve as extra hands if necessary. Their teeth are also fused into a beak-like shape, which only adds to their bird-like form. Their "hair" is typically black in color, with streaks of blue or purple. The skin of a bentoite is white, or a very light gray color.
Benitoites are gems perfectly designed for scouting. Being the only gems to bear a digitrade leg design, they are able to move quickly across great distances and jump great heights with minimal effort. Their toes are prehensile, allowing them to perch on high branches to keep a lookout for any foes with their keen vision. When running, their plume-like hair presses down against their back to ensure a perfectly streamlined and aerodynamic shape. Longer-haired Benitoites can use their hair to glide.
