Zanj Sun Squirrel (Heliosciurus undulatus) lives in tropical savanna across Sub-Saharan Africa. It feeds on fruits and nuts.
Fascinating facts about the Zanj Sun Squirrel
- The Zanj sun squirrel's tail extends well beyond its body, being about one-fifth longer than the combined head and body length. It is a slender ribbon that displays a striking pattern of ten to fourteen black bands alternating with pale ones. On average the tail measures 281 mm, while the head-body length averages 233 mm, giving the tail a clear size advantage. This distinctive tail helps identify the species in its forest habitat.
- An adult Zanj sun squirrel measures roughly 233 mm from the tip of its nose to the base of its tail, yet its tail reaches about 281 mm, making it noticeably longer than the body. This length difference corresponds to the tail being roughly twenty percent greater than the head-body combination. The proportion gives the animal a balanced silhouette that aids in agile movement through the canopy. Such a tail length is a characteristic feature noted by observers.
- The Zanj sun squirrel occupies a narrow stretch of eastern Africa, being found in south-eastern Kenya and north-eastern Tanzania, including the islands of Mafia and Unguja, but it is absent from the nearby island of Pemba. Within this range it is most frequently recorded in coastal forests and riverine gallery forests, habitats that provide the fruits, leaves and seeds it relies on.
- The Zanj sun squirrel is primarily a coastal-forest species, with most sightings coming from coastal forests and riverine gallery forest across south-eastern Kenya and north-eastern Tanzania. It has also been recorded on the slopes of Mount Kilimanjaro at elevations below 2 000 m.
- Populations of the Zanj sun squirrel persist within a network of protected lands, notably Arabuko Sokoke National Park in Kenya and Jozani Chwaka Bay National Park on Unguja's south region of Tanzania. These reserves safeguard fragments of the coastal and riverine forest that the species depends on. Because the impact of habitat clearance, charcoal production and other threats is unclear, the IUCN classifies the squirrel as Data Deficient.
