Plethodon cinereus
  • No free swimming larva stage, larva develops within egg and hatches as tiny replica of adult
  • 2 distinct phases: the red-back phase has a broad, red stripe down the back and tail; the lead-back phase has a dark grey or lead-coloured back
  • Eggs: laid terrestrially in clusters concealed under rocks or attached to cavities in logs or stumps; female broods the eggs and developing embryos; bacteria on skin produce antibiotics that protect eggs and developing embryos from fungus
