 Record Description This image shows a very pale, straw coloured, Common or Smooth Newt (Triturus vulgaris) at rest on algae in the stream which meanders through the Black Bog on Crosby Ravensworth Moor. When first seen, I thought that this pale ghost of a creature was a troglodyte emerging into daylight from the limestone fissure from which the small stream emerges as the Source of the River Lyvennet. However, I now understand that this pale colour is within the usual range of colouration of this species.

 Additional Notes Reference: T.T. Macan and E.B. Worthington. 1951. 'Life in Lakes and Rivers'. The New Naturalist Series. Collins. Three species of newts are native and widespread across Britain, the Great Crested Newt is most abundant in Southern England, the Palmate Newt at higher latitudes and also at higher altitudes. The Common or Smooth Newt (T. vulgaris) is not the most common of the three in many areas. During April, these creatures seek ponds or low energy streams and are aquatic for a few weeks and live an existence quite different from their terrestrial way of life.
