Jentink's dormouse (Graphiurus crassicaudatus)

A small African dormouse in the family Gliridae, native to West and parts of Central Africa; arboreal and nocturnal, largely associated with moist lowland forest and little-known in conservation status.

Jentink's dormouse (Graphiurus crassicaudatus) is a small nocturnal rodent in the family Gliridae and part of the diverse African dormouse group. It is conventionally treated as a species of dormouse rather than a typical mouse or rat; general references use the term rodent when placing it in broader mammal lists. The specific name crassicaudatus is derived from Latin and can be translated as "thick-tailed," a descriptive contrast to some of its slimmer-tailed relatives.

Identification and biology

This dormouse is small and mouse-like with a relatively bushy or robust tail, large eyes adapted to night activity, and soft fur that varies in tone across its range. Like other members of its genus, it is largely arboreal, skilled at climbing and typically found in the understory or canopy. Behavioural traits reported for Graphiurus species—nocturnality, a diet combining fruits, seeds, insects and other invertebrates, use of tree cavities or nests for shelter, and occasional torpor during unfavorable conditions—are likely applicable to Jentink's dormouse, although direct, species-specific studies are limited.

Range and habitat

Jentink's dormouse occurs in parts of West and nearby Central Africa. Confirmed records include several countries:

There are also occasional or unconfirmed reports from nearby countries such as Benin, Equatorial Guinea and Sierra Leone. Its natural environment is associated with forest habitats, particularly subtropical or tropical moist and lowland forests, where tree cavities and dense vegetation provide food and shelter.

Conservation and research needs

Compared with better-known African mammals, Jentink's dormouse is relatively little studied. Available information on population size, trend and precise habitat requirements is sparse. Because it depends on forest habitats, ongoing loss and fragmentation of West African lowland forest is a plausible concern. Conservation assessments would benefit from targeted field surveys to clarify its distribution, ecology and threats.

Distinctive features for field recognition include its nocturnal habits, arboreal behavior, and the comparatively sturdy tail implied by its scientific name. For more detailed taxonomy, range maps and specimen records consult specialist mammalogy sources and regional faunal guides linked above.
