A Newt with a Frog’s Mouth

  • Ernst Hadorn


Though freshly hatched amphibian larvae still possess no legs to grasp with, they nevertheless are able to stabilize themselves by holding fast to nearby objects. The tadpoles of anurans (tailless or frog-like amphibians) can anchor themselves to plants, rocks or even the film on the water’s surface with the aid of an adhesive secretion from a pair of bowl-shaped suckers (S, Fig. 26b). In the larvae of the urodeles (tailed amphibians) this attachment function is performed by slender balancers (B, Fig. 26a). These early larval grasping organs regress later on, after the limbs have sprouted forth.
