Great Pond Snail
The great pond snail is the LARGEST of  British  freshwater snails. A group of single-shelled molluscs  related to the land snails which can get oxygen from the air using a single lung. The air is taken in at the water surface through a breathing gap, and  kept in a cavity lined with blood vessels while the snail goes back under the water to feed. In well-oxygenated waters it can stay underwater for a long time.

                A saw-Scaled Viper
A viper is a snake with the most highly evolved of all poison apparatus. It is a shy creature as I only saw half of it. It is called a "saw- scaled" viper because the scales on it's side are jagged like a saw. It has two tiny eyes and a sense of smell like death. I saw the viper in the undergrowth to the left of the main pond. The patterns down it's back were white diamonds with black rings around them. It has two small white beady eyes with tiny black dots for pupils, it also has like a trident mark on it's head.
