Fig. 3. Types of branch `grips'. Overhead view of the snake on the branch, with the
anterior body of the snake hanging off the right side and below the branch
(into the page). The location of the snake's vent is represented by a yellow
dot. (A) Most common grip configuration. Grips generally comprised at least
one loop with two points of orthogonal contact (gray arrows). (B) Grip with
the first loop hanging from the branch, with the middle of the loop (gray
arrow) not contacting the branch. (C) Grip with posterior body and tail
wrapping under the branch in a spiral (gray arrow), used less frequently than
A or B. In some trials, the snake threw multiple wraps around the branch in a
more circular fashion.
