Figure 2 in Terrestrial and communal nesting in Eupemphix nattereri (Anura, Leiuperidae): interactions with predators and pond structure
Figure 2. Several aspects of the predation of Eupemphix nattereri by the whistling heron (Syrigna sibilatrix). Above: a couple of herons, each one with an adult E. nattereri in the beak. Middle: a male heron with an amplectant pair of E. nattereri in his beak (the male frog did not release the female and both escaped predation). Below: a female heron washing an adult E. nattereri prior to consumption; note the foam released by the frog while being washed. Note also in the above and middle pictures, the communal foam nests at the pond's margin. More illustrations on several aspects of the natural history of the species are at the Amphibiaweb (http://elib.cs.berkeley.edu).
Figure 1 in Terrestrial and communal nesting in Eupemphix nattereri (Anura, Leiuperidae): interactions with predators and pond structure
Figure 1. Above: foam nest anchoring in Eupemphix nattereri. Note that the foam nest (, 40 h old) is on a platform excavated in the soil and far from the water level (thin arrow). There are also platforms (thick arrow) to the left that are unoccupied. Bar,9 cm. Below: a nearly 40-h-old collapsing foam nest. Note the wet mucous string through which the early tadpoles moved towards the water. Scale bar, 6 cm.
