Answer: B) Giraffe Explanation: Giraffe has the highest blood pressure among animals.  This is due to the fact that there is a large pressure drop (~100 mmhg) as the blood is transported from the heart, up the neck, to the brain. This is about twice the normal blood pressure of humans (120/80 mmhg).
