The Large Psammodromus – Psammodromus algirus – Lagartija Colilarga can have a body length of up to 9cm with a slender tail that is two or three times longer. Its back is a soft brown with two pale yellow or off white stripes running down each flank. The back legs up to the beginning of the tail are a soft orange colour, all of this helps them to blend well with fallen leaves and soil shades under bushes which is where they are normally seen. This can be in forests, woods or more open scrubland but generally not far from shrubs that they can hunt through and use as shelter. They are very agile and can even be seen climbing nimbly through gorse bushes, often only giving away their position as they rustle through leaves. This species is very adaptable and can inhabit areas from sea level up to 2600m in altitude in the warmer southern areas of their distribution range.
