Olive Grass Snake
In this sequence we see an olive grass snake (Psammophis phillipsi) swallowing what appears to be a girdled lizard (Cordylus sp.). The girdled lizard has a very spiny tail and rolls into a ball when threatened which is what it appears to be trying to do.
Note that the snake is swallowing the lizard head first. It would be almost impossible to swallow if the spines on the tail and body were facing in the wrong direction. It is also noteworthy to observe how wide the snake can open it’s mouth to swallow large prey. This is made possible by unhinging the lower jaw which is maneuvered back into place once the prey has been swallowed.
