 <unk> salamanders in the family Plethodontidae are terrestrial and lay a small number of unpigmented eggs in a cluster among damp leaf litter . Each egg has a large yolk sac and the larva feeds on this while it develops inside the egg , emerging fully formed as a juvenile salamander . The female salamander often broods the eggs . In the genus <unk> , the female has been observed to coil around them and press her throat area against them , effectively massaging them with a mucous secretion .
