The false canyon mouse or Coronados deer mouse (Peromyscus pseudocrinitus), is a species of

critically endangered
".

Description

The false canyon mouse grows to a total length of about 194 mm (7.6 in) including a tail of 110 mm (4.3 in). The dorsal fur is greyish-black glossed with cinnamon, and the underparts are white. The tail is scantily clad with hairs; the top half is blackish while the bottom side is pale, except for near the tip where it is dark both above and below. The skull resembles that of the canyon mouse (Peromyscus crinitus) but is longer and narrower. The false canyon mouse has the darkest colouring of any of the members of the genus Peromyscus that live on the string of islands in the Gulf of California.[3] Similar mice inhabit other islands in the Gulf and the colour of each species tends to resemble that of the surrounding rocks and sand; the rocks on Isla Coronados are dark.[4]

Distribution and habitat

This mouse is

endemic to Coronados Island in the state of Baja California Sur, Mexico.[1] This is an uninhabited island, a strip of land of volcanic origin some 3 km (1.9 mi) long and 2.5 km (1.6 mi) wide. The east side of the island has steep cliffs, and the southwestern corner has a long sandy spit that stretches away towards the mainland. The island has much rock and the vegetation is arid scrub. The mice are to be found burrowing in the sandy spit and living among the rocks.[1]
