The anatomical characteristics of the lowland streaked tenrec (Hemicentetes semispinosus) (G. Cuvier, 1798) remain poorly documented, largely due to the limited availability of specimens. In particular, the species lacks a comprehensive anatomical description of its major organ systems. This study aimed to address this gap by providing a comprehensive description of the major anatomical structures of H. semispinosus. Gross anatomical examinations were conducted on sixteen specimens (6 females, 10 males), complemented by histological examinations of selected organ systems. The investigation included morphometric analyses, detailed characterisation of the skeletal system, and an in-depth assessment of the internal anatomy, including the principal organs and organ systems. The findings provide new anatomical insights and expand the existing limited knowledge of this species. The study documents anatomical features across multiple organ systems and provides additional data for comparison with other tenrecids. This work provides a valuable foundation for future anatomical, morphological, histological, and comparative studies of H. semispinosus and other members of the family Tenrecidae.
