Frogs & Toads Quiz
Poison dart frogs, bullfrogs, metamorphosis, and amphibian decline
Poison dart frogs, bullfrogs, metamorphosis, and amphibian decline
The wood frog freezes solid every winter — its heart stops, blood stops flowing — and thaws back to life in spring with no cellular damage. Frogs and toads (order Anura) are the most species-rich order of amphibians, with over 7,500 described species found on every continent except Antarctica. This quiz covers anatomy, life cycles, extraordinary adaptations, the most poisonous animals on Earth, and the global amphibian crisis.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll learn how poison dart frogs obtain their toxins from insects, why wood frogs can survive freezing, the difference between frogs and toads, the devastating impact of chytrid fungus on global amphibian populations, extreme species from the goliath frog to the 7.7 mm Paedophryne amauensis, and remarkable strategies including mouth-brooding, freeze tolerance, and arboreal life.
The golden poison frog (Phyllobates terribilis) from Colombia is considered the most toxic frog on Earth. A single individual carries enough batrachotoxin to kill approximately 10 adult humans. The Emberá Chocó people have traditionally used its secretions to poison blowdarts for hunting.
The frog/toad distinction is informal and not taxonomic — all toads are frogs. Typically, "toads" are members of family Bufonidae with dry, warty skin, shorter legs, and eggs laid in chains rather than clumps. "Frogs" tend to have smooth moist skin, longer legs for jumping, and lay eggs in masses. But many exceptions exist across the 7,500+ species.
Chytridiomycosis is an infectious skin disease caused by the fungus Batrachochytrium dendrobatidis (Bd). It disrupts the frog's ability to regulate water and electrolytes through its permeable skin, causing heart failure. It has driven over 90 amphibian species to extinction since the 1980s and has affected hundreds more — making it the most destructive infectious disease ever recorded in vertebrates.
