Tess Thompson Talley has faced anger from animal rights campaigners over her photos of a dead giraffe she killed.
An adult giraffe head can weigh 30 kg (66 lb), and if necessary, male giraffes establish a hierarchy among themselves by swinging their heads at each other, horns first, a behavior known as "necking". A subordinate okapi signals submission by placing its head and neck on the ground. Giraffes are sociable, whereas okapis live mainly solitary lives.
In okapi, the male's ossicones are smaller in proportion to the head, and taper towards their tips, forming a sharper point than the comparatively blunt giraffe ossicone. Whereas female giraffes have reduced ossicones, female okapi lack ossicones entirely. The morphology of ossicones in the extinct relatives of giraffes and okapi varies widely.
