![]() ![]() Sometimes, the researchers personally recorded the giraffes, but they relied on autonomous recording devices for the longer night recordings. To investigate, the researchers recorded a total of 22 giraffes at three European zoos - the Berlin Tierpark, the Copenhagen Zoo in Denmark and the Vienna Zoo. But there's inconclusive evidence for this idea, prompting Stoeger and her colleagues to start recording giraffes in an effort to learn more about the noises they make, and whether those noises are used for communication. ![]() Or maybe giraffes produce sounds in the infrasonic range - much like the rumble of elephants - that are below the threshold of human hearing, she said. "There have been suggestions that the giraffe's iconic long neck makes vocalization physically impossible, due to the difficulty of sustaining the required airflow from lungs to mouth over such a distance," Stoeger told Live Science in an email. They can go for long periods without water, and regularly go for days without a drink.The giraffe's neck may explain why the animal doesn't say much. This is a vulnerable positionįor them, and herd members will take turns looking out for predators while others drink. Them awkwardly wide, especially to drink. Their legs are so long, they must either bend the front legs, or spread Heads and graze off the ground if something is tempting enough. They spend almost all of their time grazing among, tallīranches for herbs, vines, flowers and fruits, but will lower their In place of the top front teeth, which they grind their food against.Īre some of the largest land animals, and need up to 70 pounds of food aĭay to survive. Giraffes have a hard thickness of tissue called the "dental pad" Leaves from their favorite tree the Acacia - which has 3 inch long Prehensile, allowing them to grasp leaves and branches, but are alsoĮxtraordinarily tough, protecting them from damage as they munch on the The giraffes top lip, and its 18 inch long tongue, are not only With this method, they get as much nutrients as they can from the leaves and fruits they consume. ![]() Like cows, giraffes have multiple stomach chambers and "chew their cud", meaning they regurgitate partially digested food back up their 6 foot long throat, to re-chew it one mouthful at a time. The head is refined, streamlined and equipped with an 18 inch long tongue for even further reach. The neck is supported by powerful muscles and reinforced ligaments which anchor to vertebrae between the shoulder blades, and form a hump where the back and neck meet. While the relatively short back has vertebrae of a median size, the vertebrae of the neck, are stretched to about 11 inches long, They still have the standard 7 neck vertebrae found in most mammals, including us, but they are not only elongated, but also articulate far more than ours. Front and rear legs are about the same length, however, between 5.5 and 6 feet long. Viewed from the side, the giraffes shoulder region is towering, with a highly elongated pectoral girdle which gives the illusion that the front legs are longer than the rear. While the 6 to 8 foot long, 600 pound neck is most obvious, the giraffes entire body is a masterpiece of specialization. Today the giraffe is the tallest animal on Earth, with males topping out at about 18 feet at the tip of the horns (called occicones), and 11 feet at the shoulder.Īlthough no fossil trail exists, it is assumed the giraffe developed its remarkable physique and out-survived its relatives, by reaching for the treetops.Īs taller individuals ate leaves and fruits unavailable to shorter individuals, the giraffe thrived, and became more and more specialized.
