Undeniable Fact: Sticking its neck out

Although we often refer to it as a "neck", the long stalk which protrudes from a giraffe's torso is technically a "sensory umbilicus" - a connection between the giraffe's eyes, ears, and nose and its brain, which is safely nestled within its chest. The giraffe is, in fact, the only warm blooded animal whose sensory organs are separate from the brain. If the giraffe's "head" is chopped off, it will simply grow back, although the sensory structures will not.
