Giraffes have a four-chamber stomach that allows them to digest food for extended periods of time, sometimes up to a day. Our goal is to make science relevant and fun for everyone.

During copulation, male giraffes stand almost straight up on their hind legs, resting their front legs along the female's flanks, an awkward posture that would be unsustainable for more than a few minutes. They are not aggressive animals and prefer to avoid conflict. Interestingly, giraffe sex can provide clues about how dinosaurs like Apatosaurus and Diplodocus had sexdoubtless equally quickly, and with roughly the same posture. 1979, 14: 103-107. 1962, 26: 497-505.
