Goodarzi N., Skeletal morphology of forelimb of Paraechinus Hypomelas (Brandt, 1836); a radiographic and 3D computed tomographic study, Onl J Vet Res., 22 (10):1003-1013, 2018. Author describes forelimb of the hedgehog Paraechinus Hypomelas (Brandt, 1836) by anatomy, radiography, computed tomography (CT) and colored prototypes, compared with Paraechinus micropus (Blyth, 1846) and Hemiechinus auritus (S.G. Gmelin, 1770). The thoracic girdle consisted of a scapula and clavicle with a pronounced acromion extending as a meta-cromion hamate process caudally. The supratrochlear foramen was incomplete and closed by an osseous membrane. Carpal bones were arranged in proximal rows with intermediate, ulnar and accessory carpals caudally and a distal row of 4 carpal bones. The first and fifth digits had proximal and distal phalanges, while other digits had proximal, middle and distal phalanges. Each digit had a pair proximal sesamoid bones on the metacarpophalangeal joint and a single distal sesamoid bones on the distal interphalangeal joint. The findings suggest that the forelimb skeleton in Paraechinus Hypomelas shows characteristics specific for fossorial habits with evidence of poor borrowing characteristics.
