In
terrestrial environments, gravity places special demands on the
cardiovascular systems of animals. Gravitational pressure can cause
blood to pool in the lower regions of the body, making it difficult to
circulate blood to critical organs such as the brain. Terrestrial
snakes, in particular, exhibit adaptations that aid in circulating blood
against the force of gravity. The problem confronting terrestrial
snakes is best illustrated by what happens to sea snakes when removed
from their supportive medium. Because the vertical pressure gradients
within the blood vessels are counteracted by similar pressure gradients
in the surrounding water, the distribution of blood throughout the body
of sea snakes remains about the same regardless of their orientation in
space, provided they remain in the ocean. When removed from the
water and tilted at various angles with the head up, however, blood
pressure at their midpoint drops significantly, and at brain level falls
to zero. That many terrestrial snakes in similar spatial orientations
do not experience this kind of circulatory failure suggests that certain
adaptations enable them to regulate blood pressure more effectively in
those orientations.

One such adaptation is the closer proximity of
the terrestrial snake’s heart to its head, which helps to ensure
circulation to the brain, regardless of the snake’s orientation in
space. The heart of sea snakes can be located near the middle of the
body, a position that minimizes the work entailed in circulating blood
to both extremities. In arboreal snakes, however, which dwell in
trees and often assume a vertical posture, the average distance from the
heart to the head can be as little as 15 percent of overall body
length. Such a location requires that blood circulated to the tail of
the snake travel a greater distance back to the heart, a problem solved
by another adaptation. When climbing, arboreal snakes often pause
momentarily to wiggle their bodies, causing waves of muscle contraction
that advance from the lower torso to the head. By compressing the veins
and forcing blood forward, these contractions apparently improve the
flow of venous blood returning to the heart.
