Hamadryas fornax (top) and Hamadryas februa (bottom) are species of cracker butterflies in the Nymphalidae family. The former is commonly known as the Orange cracker, while the second as Grey cracker. Both are Neotropical butterflies.
The Hamadryas baboon is unusual among baboon and macaque species in that its society is strictly patriarchal. The males limit the movements of the females, herding them with visual threats and grabbing or biting any that wander too far away.
Aging males who lose females in their harem to young males soon lose weight and their hair color changes to brown like a female.
The Hamadryas is the northernmost of all the baboons, being native to the Horn of Africa and the southwestern tip of the Arabian Peninsula. It was a sacred animal to the ancient Egyptians and appears in various roles in ancient Egyptian religion, hence its alternative name of ‘sacred baboon.’
