Notophthalmus viridescens

Newt, Notophthalmus viridescens adults, single acute exposure of 20 Gy, one limb shielded or 22 Gy, whole body, no limbs shielded Frog, Rana sp., single acute exposure Forelimb regeneration completely suppressed when limbs to be amputated were irradiated directly. Irradiated limbs had severe and protracted inflammation, with total resorption of the affected limbs in 85% of the cases. Shielded limbs subsequently amputated had delays — but not suppression — in rate of forelimb regeneration and skin graft rejection 4...

A non-toxic species of salamander may derive protection from predators by visually resembling a toxic form so closely that predators cannot distinguish between them Batesian mimicry). Free-ranging birds avoid both the toxic red eft Notophthalmus viridescens) and the similar-looking non-toxic red morph of the red-backed salamander Plethodon cinereus). The red-striped morph of P. cinereus, which does not resemble the red eft, is eaten (Brodie and Brodie, 1980).

In the case of the red-spotted newt (Notophthalmus viridescens) of North America, the red eft is the stage that occurs after transformation of the aquatic larva. The red eft is bright red or orange, and is a pre-reproductive adult stage. The red eft wanders widely in forests, sometimes for several years, and is most common on moist nights. Eventually, the red eft migrates to an aquatic...
