These animals typically weigh < 1 kg, have compact and rounded bodies, short noses, a disproportionately large head when compared to rest of the body, and small ears. (C and D) Newborn dw/dw individual (peanut) side by side with a Dw/dw (dwarf) littermate. dw/dw animals are born smaller than their littermates and have a disproportionate body conformation with cone-shaped heads, small ears and limbs, and prominent eyes, which are evident at the time of birth. (E) Detail of the head of a dw/dw individual. Photo credits: (A) Sara Gutiérrez Albarran; (B–E) Javier Lopez.
