Tastier than thought? Telemetric research reveals predation on the poisonous yellow‐bellied toad Bombina variegata.

As predation by grass snakes was the most common cause of mortality in this study, the inference to be drawn is that the yellow-bellied toad's aposematic coloration is not sufficient defense against these snakes. Telemetric research reveals predation on the poisonous yellow-bellied toad Bombina variegata The most common predator of adult yellow-bellied toads turned out to be the grass snake I Natrix natrix i (Figure 1c), which devoured toads with transmitters attached to them. The reason for the extremely limited data on the predation of adult yellow-bellied toads may lie in the difficulties of actually observing predation in the wild. [Extracted from the article]
