I saw a DVD titled "Caught in the Act", and it featured two giraffe that were sparring. One of the giraffes planted a well aimed shot to the other and promptly knocked his opponent unconcious for a second or two. The giraffe dropped like a sack of potatoes, layed there for a bit before struggling to get up.

This is not a high kick. The giraffe at the back or on the leaft had a swipe at the other ones legs which then got stuck behind its head and very nearly dump him over as he straightend up. In the KTP.

I recently learned that giraffe babies are born with horns on their haed (although they are not yet connected to their skulls, as to not injure their mother's uterus). I did a quick reserach on the net and now I am not sure if giraffes are the only animals which give birth to babies with horns or if they are one of the few animals that do so? clarification would be appreciated!

Hi Ice,

The other species seems to be the oryx:

Giraffes and Oryx born with horns. Giraffe horns lay on the skull, become erect after about a week. Oryx horns visible at birth as hair-covered bumps.

Interesting fact about the giraffe is its head cannot go below its hart because it wil die of to much blood on the brain and thats whay thay go down like thay do when thay drink.

Thay have a netting of veins behind there brain that keeps the blood away from the brain for 60 seconds so htat thay can drink.

Thats whay you will never find a giraffe drinking longer than 60 seconds.!!!

Wildlover, no, not quite. The simple reason for them going down like that to drink is that their neck is shorter than their front legs and body combined so, unless they bend funny like that, they'll never be able to drink.

When they drink their heads do go below their heart. But you're correct, if they didn't have a system in place they would die, and then on the flipside pass out should they suddenly get up as there wouldn't be any blood.

Here's a shot off the webcams that Imberbe posted some time ago on a quiz, showing how low the head goes.

Image

And off there the answer also comes in terms of why don't die of stroke, nor pass out:

Quote:
A giraffe's heart, which can weigh up to 10 kg (22 lb) and measure about 60 cm (2 ft) long, has to generate around double the normal blood pressure for an average large mammal in order to maintain blood flow to the brain against gravity. In the upper neck, a complex pressure-regulation system called the rete mirabile prevents excess blood flow to the brain when the giraffe lowers its head to drink. Conversely, the blood vessels in the lower legs are under great pressure (because of the weight of fluid pressing down on them). In other animals such pressure would force the blood out through the capillary walls; giraffes, however, have a very tight sheath of thick skin over their lower limbs which maintains high extravascular pressure in exactly the same way as a pilot's g-suit


Quote:
That is the secret! It is also called a "blood sponge".

It is a unique (if I remember correctly the Okapi has a similar but only very rudimentary one) and very intricate system the giraffe developed. Basically it is an organ sitting just below the brain, with many blood vessel, which is packed closely together. As the blood pressure increases when the giraffe bends down, the increased pressure forces the vessels closer together. This hinders the flow of the blood by constricting the vessels. This blocks the higher pressure and limits the amount of blood coming through, protecting the brain, while at the same time ensuring that enough blood do reach the brain for it to continue functioning normally.


Wonderful animals indeed!!

This leucistic Giraffe was seen in Kruger just below Lower Sabie in May this year.

Interesting sighting Elsa.
Looking through my earlier photos I came across this Giraffe which shows just how supple a Giraffes neck is. This photo was taken way back in Nov 2005 and I have not witnessed anything like this since.
