On the morning of 29 April, three dead males and a moribund male in amplexus with a dead female were
found, and a smaller chorus started again at dusk. Potamid crabs (Fig. 2B) predated and scavenged eggs and frogs.
It seemed that the crabs preferred the viscera, and they reached into the opened body cavities to remove pieces of
tissue that looked like pieces of the fat bodies. In one case, a crab began to chew on the right hind leg of a calling
male. The frog made several futile leaps while dragging the crab with him but could not escape until the approach
of a second crab caused the attacker to release its grip. While the two crabs fought, the frog hurriedly escaped into
the forest.
