The Cursor Grass Mouse or Cursorial Akodont (Akodon cursor), is a rodent species from South America.[2] It is found in Argentina and Brazil.[1]
Description
The cursor grass mouse is a moderately sized rodent, with a head-body length of 11 to 13 centimetres (4.3 to 5.1 in), and a tail 8 to 11 centimetres (3.1 to 4.3 in) long. Males are larger than females, weighing an average of ((convert|54|g}}, compared with 43 g (1.5 oz) for females. They have a typical mouse-like appearance, with short whiskers and stubby claws on the feet. They dark to golden brown fur over most of the body, with paler greyish or yellowish underparts. Some have a whitish spot between the ears, but this is not present on all individuals.[3]
Cursor grass mice are members of the A. cursor species group, and very similar in appearance to other members of the group. In particular, they cannot easily be distinguished from the closely related montane grass mouse, which inhabits neighbouring regions to the immediate south. Although the cursor grass mouse is, on average, slightly larger than the montane species, there is too much overlap for this to be a reliable guide. Instead, they can most readily be distinguished by the presence of a gall bladder in A. cursor (absent in the montane species), or by karyotypic analysis.[3][4]
