Phocomelia
A congenital malformation (birth defect) in which the hands and feet are attached to abbreviated arms and legs.
The word phocomelia combines phoco- (seal) and melia (limb) to designate a limb like a seal's flipper, one consequence of exposure of the developing fetus to thalidomide.
Phocomelia may also in some cases be genetic (as in the Roberts tetraphocomelia syndrome)
