The tadpoles of the microhylid Scaphiophryne gottlebei and of the
mantellid Mantella expectata from the Isalo Massif (south-central Mada-
gascar) are described and compared with already known tadpoles belonging
to the same genera. The tadpole of S. gottlebei is peculiar in having the oral
apparatus with a horny beak surrounded by dermal papillae, and a spiracle
in intermediate position, between ventral and lateral. Furthermore, it shows
unique feeding habits and a peculiar associated behaviour. During the day it
stays close to the bottom and often burrows half of the body into the sand
with the tail obliquely upwards; in this position it ingests organic material
