8. Don’t wrinkle your nose — that goo may one day save your life. In March, researchers announced long-lasting, non-toxic túngara frog foam could be the perfect delivery method for antibiotics and other drugs used to treat severe burns.
9. While some frogophile elitists may claim there is a difference between frogs and toads, science doesn’t formally recognize one.
10. That said, just like ranids are often called “true frogs” colloquially, members of the Bufonidae family within Anura are called “true toads.”
11. One thing that’s not true about toads is that they have anything to do with toadstone. First mentioned by Pliny the Elder in the first century as “frog stones,” people believed these small, dull-colored objects were talismans that had all kinds of medicinal and magical value.
12. Science check: They’re actually just fossilized teeth of the fish Lepidotes.
13. What makes a toad “true,” then? Thick, warty skin and a lack of teeth, plus a Bidder’s organ. The latter is a mysterious, ovary-like structure that is present in both sexes of bufonids during development, but in adulthood remains only in males.
14. First described in 1758, the exact function of the Bidder’s organ remains unknown.
15. Something else that remains unknown about true toads, true frogs and all the other anurans: how they will fare against increasing habitat destruction and climate change. A 2015 study suggested that extinction rates for frog species have increased fourfold since the 1970s.
