Frog in the Throat?

Yet another unique Australian species threatened by biocontrol- gone-wrong (https://www.theguardian.com/environment/2018/jul/28/australia-northern-quoll-endangered-cane-toad). Cane toads (with their toxic skin secretions defence) were imported from South America to deal with beetles that were causing problems in sugarcane plantations. Although this was not very successful, the toads thrived in this new location but their toxins are killing off any animal that eats them. This has happened with indigenous snakes who have responded, in some cases, by developing a gape too small for a toxic toad. Now the marsupial predator, the Northern quoll, is said to be decimated by their preference for toad (not in the hole). Scientists are attempting to wean them off this dietary item.
