Snake and lizard - not for the squeemish

Just as we were leaving work, we heard a plop in the driveway and went to see what it was. It is a Brown House snake who had found a Speckled Rock Skink.
What was amazing was the fact that no matter what the skink did, the snake made sure that part of his body was always across the skink in order to hold it down and it could not move.
All snakes have a lower jaw which they can unhinge and if you have a look at the mouth in this series of pictures, you can see how it stretches to accommodate the size of his prey which is at least 5 times bigger.

Brown House snakes are medium sized and less than 3 feet in length. They have no fangs and are not venomous an so constrict their prey.
Once the prey is ingested, the stomach fluids dissolve the prey and all which is left is a small, cylindrical pellet which they regurgitate.
Because of their slow metabolic rate, reptiles need to eat less frequently than other animals or humans and can go for long periods without food, especially in the winter.
