Giraffe and human metacarpals compared [1]
Here’s one of my most prized possessions: a cannon bone from a giraffe. I got it last fall from Necromance, a cool natural history store in LA
Jessie Atterholt got one of them last summer, and I got the other a few months later.. The cannon bones of hoofed mammals consist of fused metacarpals (in the forelimbs) or metatarsals (in the hindlimbs)
Only my third metacarpal is traced in the top photo. For maximum homology goodness I should have traced MC4, too, but I’m lazy.
How many bones are in a cow’s body? [2]
A cow’s skeletal structure consists of approximately 207 bones. The variation in number is found in the tail, where cattle have between 18 to 20 vertebrae.

The Skeleton of Giraffes [3]
The dry mass of the skeleton is 70 g.kg-1 body mass. The average chemical composition of their bones is 33% minerals (mainly calcium and phosphorus in a ratio of 2:1), 34% collagen, and 33% water
The average density of all bones is 1.6 g cm-3, ranging from 0.8 g cm-3 (cervical vertebrae) to 2.0 g cm-3 (limb bones). Resistance to fracture by vertebrae depends on their cross-sectional area, and is greatest in cervical and the first few thoracic vertebrae
The growth of all limb bones except the humerus follows a geometric pattern (length and diameter increase at the same rate) which confers resistance to compression stress. The humerus follows an elastic pattern (diameter increases faster than length) a pattern that resists bending stress
Truth or Tail: Giraffe have more neck bones than a human. [4]
Even though the neck of a giraffe can be eight feet long and weigh up to 600 pounds, they only have seven neck vertebrae – the same number of neck bones that humans have! But unlike our vertebrae, each of theirs can be up to 10 inches long. These large vertebrae link together to form those famous long necks we all know and love
This decreases food competition between them and other plant-eating animals. Their long necks also help them spot distant predators
Lastly, male giraffe will use their long necks to compete with other males. They do this by swinging their necks against each other in a behavior called ‘necking’
How Many Bones Does A Giraffe Have – Animal Thrill [5]
There are four distinct species of giraffes, but they all have the same number of bones. Looking at a giraffe’s neck, in particular, can lead to some wild speculation about its bones because it seems like there should be quite a few.
A giraffe has 208 bones throughout its body, which is only 2 more than humans. They have 7 bones or cervical vertebrae in their long neck, but the rest of their back has several different types of bones which include vertebrae, ribs, and the sacral foramina
Surprisingly, that is the same number of bones you or I have in our necks. The difference isn’t the number but the size of those bones
If a giraffe’s neck only has seven vertebrae, how is it so flexible? [6]
Certain characteristics of giraffe necks give them a flexibility rivaling any Slinky. The first feature is the way that the vertebrae in the neck, called the cervical vertebrae, are joined together
However, giraffe cervical vertebrae are bound together with ball-and-socket joints [source: Owen]. These are the kinds of joints that link your arm with your shoulder and offer a 360-degree range of motion
Moving down to where the neck meets the back, we find the second important anatomical feature for the giraffe’s slinkiness. We call the vertebrae in the top portion of our backs the thoracic vertebrae
How is a mouse like a giraffe? [7]
You will be able to access your list from any article in Discover.. Mice and giraffes may look like they could not be more different from each other
There are thought to be over 5,400 species of mammals living on Earth. They come in all shapes and sizes – from tiny mice to towering giraffes, and scale-covered pangolins to 100-tonne whales.
Watch as senior curator of mammals Louise Tomsett explains the surprising similarity between mice and giraffes.. Mice and giraffes live drastically different lives – not to mention that giraffes tower over mice by over five meters.
How many bones are there in a Giraffe’s neck? [8]
Hint: Bone is a type of connective tissue that constitutes the framework of the human skeleton by- providing support and structure to the body.. Giraffes are the tallest living terrestrial mammals and the largest ruminants present on our planet
It belongs to the only two living genera of the Family Giraffidae. They primarily live in the savanna regions of Africa
They are Osteophagic, which means they feed on bones.. Bones are the mineralized connective tissue that is made up of calcium and bone cells
Incredibly, Birds Have More Vertebrae Than Giraffes [9]
Giraffes are a species of animal famous for their long necks and incredible height. There are nine subspecies of giraffes that separated into individual groups around two million years ago.
It would make sense that they’d have more vertebrae in their necks than little birds but they don’t. Incredibly, birds have more vertebrae than a giraffe!
The exact size, placement, and shape of vertebrae vary depending on the needs of a species. Each vertebra is specifically designed to align with the other vertebrae so nerves and the spinal cord run through it.
How many bones does a giraffe have in its neck? [10]
The giraffe, just like a human has seven neck vertebrae . For giraffes, however, each one can be over 10 inches (25.4 centimeters) long
The legs of a giraffe are also 6 feet (1.8 meters) long. The back legs look shorter than the front legs, but they are about the same length
The giraffe’s chief distinguishing characteristics are its extremely long neck and legs, its horn-like ossicones, and its distinctive coat patterns. It is classified under the family Giraffidae, along with its closest extant relative, the okapi
I Wish I Had As Many Neck Bones As A Giraffe… [11]
Besides being carbon-based, warm-blooded, possessing fur and secreting milk… most mammals have 7 cervical vertebrae. That’s right, with the exception of sloths and manatees, from every giraffe to every mouse… we all have 7 cervical vertebrae
The evolution, or epigenesis, of the elongated giraffe neck, is interesting. Obviously there is benefit in the ability to outcompete shorter-neck herbivores for high hanging vegetation
A newer theory even suggests that a giraffe’s neck may help them regulate their body temperature in hot African climates by increasing their body surface area to allow heat to escape. They also are a “cylindrical animal”, so they can turn their “flat” sides away from the direct equator sunlight to reduce the amount of heat on their skin.
Giraffe neck is longer than thought [12]
Giraffe neck is longer than thought Anatomical evidence for giraffe’s eighth “neck” vertebra. Researchers at the University of Tokyo demonstrated that the first thoracic vertebra of giraffe acts like a cervical vertebra
The giraffe possesses a unique body plan with an extraordinarily long and flexible neck. However, the giraffe neck, like the human, basically consists of just seven bony cervical vertebrae
Megu Gunji and Professor Hideki Endo at the University of Tokyo dissected giraffe carcasses donated from zoos around Japan, and described the musculoskeletal structure around neck-trunk junction of the giraffe. They found modifications of the musculoskeletal structure in this region, and demonstrated that the eighth vertebra (first thoracic vertebra) of the giraffe possesses high mobility similar to the cervical vertebrae
San Diego Zoo Animals & Plants [13]
Hello up there! Why do so many people look up to giraffes—besides the obvious reason? The long and short of it is that they are a wonderful example of nature’s creativity.. A giraffe could look into a second-story window without even having to stand on its tiptoes! A giraffe’s 6-foot (1.8-meter) neck weighs about 600 pounds (272 kilograms)
The back legs look shorter than the front legs, but they are about the same length. A giraffe’s heart is 2 feet (0.6 meters) long and weighs about 25 pounds (11 kilograms), and its lungs can hold 12 gallons (55 liters) of air! Its closest relative is the okapi.
For a long time people called the giraffe a “camel-leopard,” because they believed that it was a combination of a camel and a leopard. That’s where the giraffe’s name camelopardalis comes from!
They’re a lot like us! [14]
An iconic species, giraffes are sensitive, gentle, social, and friendly. We want you to get to know and love these magnificent beings, just like we do.
However, a typical human neck is a mere 4.3 inches in length, while a giraffe’s is 6 feet long with vertebrae that can measure more than 10 inches each.. They spend much of the day eating, consuming up to 75 pounds daily
But just like the gourmets among us, giraffes eat flowers, too!. Okay, it’s not really insomnia, but they are only in deep sleep on the ground with their necks curled back resting their heads on their rumps for 2-6% of the night!
Giraffes have the same number of neck bones as humans. [15]

Why Do Giraffes and Humans Have the Same Number of Neck Bones? [16]
The world is populated with an amazingly diverse animal kingdom, each species possessing its own unique features that help them survive and cope with their surroundings.. There’s the cheetah with its incredible burst of speed, the albatross that has a wingspan of over 3 meters and the groundhog which is the largest member of the squirrel family.
And then there’s the giraffe, the animal with the longest neck in the world.. There are few things that are quite as magnificent as seeing a giraffe in the wild
The tallest one on record was around 19.3 feet, about the size of an average house, maybe a little higher. It’s the elongated neck that grabs most of the attention, though, and that alone can weigh as much as 550 lbs.
7 Things You’ve Always Wondered About Giraffes [17]
How many vertebrae, or “neck bones” do you have in your neck? 7! How many does a giraffe have? 7! How about a dog? 7! And a cat? 7! Starting to see a trend here….the only mammals that don’t have 7 are sloths and manatees, but that’s a different story. For giraffes, however, each cervical vertebrae can be over 10 inches long!
Giraffes amazing tongue is a uniquely adapted tool to help it reach food. The tongue can measure 18 to 20 inches long and is what is known as “prehensile” allowing it to wrap around branches and pull leaves off
Giraffe ‘horns’ are not actually called horns, but ‘ossicones’ and both female and male giraffe have them. Ossicones are formed from ossified (hardened into bone) cartilage and are covered in skin.
Osteological Reproductions [18]
Artiodactyls or even-toed ungulates (mammals with hooves) appear in the fossil record in the early Eocene (56 – 47 million years ago) and posses a specialized skeleton for a terrestrial environment and herbivore dentition. Included in Artiodactyla order are giraffes and okapi
They have 7 cervical vertebrae, each about 10 inches long. The okapi is the only living relative of the giraffe

Giraffe Anatomy 101 [19]
Weighing up to two tons, the giraffe is a colossal animal and unlike any other. Julian Fennessy walks us through the giraffe’s unique anatomy by examining the bones of a enormous male specimen.
Julian Fennessy walks us through the giraffe’s unique anatomy by examining the bones of a enormous male specimen.. There’s no claw marks on him like from a lion or anything.
JULIAN: they actually are like cartilage like in your ear and when they’re born they’re flat, and then they fold out and they become bone and fuse to the skull.. The males’ ossicones are much larger, and grow increasingly massive over their lives.
