what kind of giraffes have you been looking at man

Reportedly they moo (that makes sense since they're ruminants), roar (that's scary), grunt, snort, growl, sneeze, snore (imagine trying to sleep next to a snoring giraffe!), bleat, hiss, whistle and cough.\nI've never heard it so I'm just trusting the sources.

Yes. In addition to their large evergrowing incisors (the tusks), they have massive molars with a crushing surface that looks like one of those old washing tables. They have 6 upper and 6 lower molariforms on each side, but only 2 of them are functioning at a given time. The others are inside the alveoli in the skull and jaw bone and come out after the first ones get completely worn. They don't have more than those 6 replacements, so when their last molars are worn, they cannot grind food (old elephants in zoos need a special soft diet).\n\nHere's a photograph showing the crushing surface of the molar teeth:\nhttp://animaldiversity.ummz.umich.edu/site/resources/skulls/loxodonta/l._africana/163809.tooth.jpg/view.html\n\nAnd a frontal view of the skull with the incisors:\nhttp://www.dundee.ac.uk/museum/zoology/bagful/1971A.JPG

haha ok i have a couple questions...\n1) how old are you?\n2) what made you think of htis question?\n3) dont you have anything better to do lol?\n\nbut thats a tough question, i would say the octopus - stronger, and with the sucker/squeegie things, they could like wrap their arms around the giraffe and take it down...hope that helps!!

because their horns don't work.

It’s made of keratin—that’s the stuff your hair and nails are made of. The horn is a pretty distinctive feature—the name “rhinoceros” is actually made of two Greek words meaning “nose” and “horn”. Tragically, rhinos are often killed for their horns. The once-large rhinoceros family has dwindled to just a few living species almost all of which are threatened with extinction.

Giraffes vocalize at an infrasound level - sound at a frequency too low to be heard by a human ear.

The elephants’ ancestors looked more like pigs than elephants, and were about that size.  As elephants’ ancestors evolved they gradually be came larger, with larger heads of course.  The neck of an elephant is very short.  A long neck would not be able hold such a heavy head.  With a short neck an elephant cannot graze like a horse.  As the elephant evolved the upper lip of the elephant became the trunk we see today.

its either the blue whale or the girraffe if thinking of relative to body size as the girraffe has to pump blood all the way up its long neck which takes a lot of pressure.\n\nsly simon or whtwever your name is, the elephant is also a mammal, and mammals are animals behave yourself!!!!

Okapi - they are related to the giraffe actually!  (they have those skin covered horns in males, and an extendable tongue, as well as similar teeth).

There are a number of misconceptions about giraffe. One is that they cannot make any sound. Although generally quiet, they have been heard to grunt, snort and bleat.

Well, some simple abiotic factors would be that giraffer's are affected by the pH of the water they drink, its salinity, body temperature, environmental temperature, as well as air qualities. I could look into the actual environmentalcontext fo the giraffe species and see what it lives around.\n\nfor biotic factors, we could say human encroachment, predation of lions, for instance. We also know that the leaves and grasses it feeds on is another biotic factor. We can look at sexual competition (if there is any) in the giraffe species, and of course any incidences of bacterial disease that a giraffe is significantly prone to.

come on peace that is not the answer.\nGiraffe are the tallest animals in the world. Males can reach as high as 6 meters (19 feet) tall and female giraffe can measure up to5 meters -17 feet) tall. Their neck accounts for the added height and is by itself approximately 2.4 meters (8 feet) in length and can weigh almost 227 kilograms (500 pounds). \n\nFUNNY THIGS :\ntallest man in the world reaches his belley.\nhe needs telescope to see his leg.\nand most of all, \ndamm...he is taller than me.\ni cant belive it.

The bull has a hump between its head and shoulders. Has more meat than fat. A Very solid animal. and suvives better in hot areas.

Been there, done this!  They are not. It's an urban legend. Besides, Elephants aren't afraid of humans, lions, or anything. Even lion prides move out of the way when the big animals comes.\n\nSnopes comments that "In fact, given the large size and relatively poor eyesight of elephants, they don't necessarily notice the occasional mouse scurrying around them all that often."\n\nAlthough it's possible that if by some fluke the mouse scurrying noise was magnified an elephant might be a little spooked and try to figure out whether it's dangerous or not.

The stapes is the oldest of the three ear bones in mammals.  Birds and reptiles only have a stapes (called a columella).  The malleus and incus are both part of the jaw.  The stapes also used to be long and thin instead of stirrup shaped.  This is still true for monotremes, marsupials, and xenarthrans (armadillos, anteaters, and sloths).  The stirrup shape is caused by the passage of an artery through the hole in the middle.\n\nThe role of the stapes is the same in epitherian placentals as it has been in reptiles.  It transmits vibration to the fenestra ovalis in the cochlea.  It's in the cochlea where differential vibration of the various hairs allows for precision of sound interpretation.  \n\nIn mammals the vibration of the stapes is transmitted from the incus.  In nonmammalian vertebrates, these vibrations are transmitted directly from the ear drum.
