walk sequence.
more pronounced during a walk than for quadrupeds that walk with a more
upright gait and without splayed legs. When moving at speed this rotation
of the body is increased to fairly extreme levels and is far more evident. The
crocodile is quite capable of moving at high speeds both on land and in the
water. When swimming, the crocodile depends in part on the undulating
action of the body, though the principle source of locomotion comes from the
undulating action of its very long and strong tail. The legs may make some
contribution to swimming, but they are generally restricted to assisting in the
creature's maneuverability.
Squirrels
The squirrel's physiognomy gives it quite remarkable agility. Squirrels are
capable of very rapid actions demonstrating extremes of acceleration and
deceleration. When running they seem capable of stopping instantly with
no deceleration at all. Their lack of mass and relatively large muscles enable
