Big Black Snake

Today I went to the local beach when the wind was so strong, and stood at the end of the path through the dune's the wind being to strong to go any further, and took a picture, there were hundreds of birds feeding on a shoal of fish, when I had finished and turned around I was horrified to see a 5 foot Black Snake crossing my path, I retreated in haste and was just able to get this picture of its tail as it disappeared into the bush
