The sasabonsam is a forest vampire which originates from the Ashanti people of Southern Ghana but is also found in Togo and the Ivory Coast.
Little is know about this creature outside of native folklore, which is prone to exaggeration and contradiction. The creature is described as about man sized with short, stubby arms, but has been reputed to have a wingspan of up to 20 feet. It is also often given iron teeth. Sasabonsams are rarely seen nowadays, but they were known to sit on treetops and catch unsuspecting passers-by to suck their blood.
Much like the kongamato, the sasabonsam may be a conflation of representatives from multiple baramins, combined with some Ashanti imagination. More research is definitely needed.
