Cuvier's gazelle
Cuvier's gazelle (''Gazella cuvieri'') is a species of gazelle found in Algeria, Morocco and Tunisia. It is also known as the edmi.〔(Ultimate ungulate.com )〕 It is one of the darkest species of gazelle in coloring, due to its partial woodland habitat. It is sometimes placed in a separate genus, ''Trachelocele'', from other gazelles, together with goitered gazelles and rhim gazelles. It is very rare in wild with only 2000 individuals.
== Characteristics ==
The Cuvier’s gazelle is one of the darkest and smallest of the gazelle species, standing tall, with an average weight of . It is characterized by a distinctive wide, dark band that runs along the sides of the animal, which separates the brown dorsal parts from the white ventral parts. While both sexes have horns between long, the males' are more ribbed and have greater mass. Also they possess long, slender ears.〔(Ultimate ungulate.com )〕
The purpose of the dark bands that run parallel along the side of the animal is to aid in countershading, having ventral body pelage that is more lightly colored that the dorsal surface. This may reduce the shadows produced by the animal’s body. The sun shining downward on the animal will cause an unequal distribution of light, disrupting the pattern created by its silhouette. The darker colors compared to other gazelles could be explained by its shadier habitats.
