    Unken reflexes

    The yellow-bellied toad (Bombina variegata) is a small toad found in ponds and calm waters of the mountains of central and northern Greece. Here's a yellow-bellied toad from the National Park of Valia Calda as it shows off the abdomen in order to deter the predator. This is a typical example of “warning colouring". The abdomen of the species is brightly yellow with dark spots and patches, unlike the back which is dark brown-gray. When the yellow-bellied toad feels threatened, it turns itself upside down and folds, showing off her yellow belly, while covering its eyes with the front paws. This behavior called “unken reflex” informs the potential predator about the poisonous nature of the whitish skin secretions.
