All About Frogs Trivia Quiz

Answer: All toads are frogs

Members of the family "Bufonidae" are the only amphibians considered to be "true toads," while members of other families are often popularly referred to as such. Frogs, including all toads, fall into the order "Anura." Other amphibians include newts, salamanders and caecilians.

Answer: Frogs lay their eggs in long chains, while toads lay their eggs in clusters

Female toads tend to deposit their eggs in long, parallel chains, while female frogs lay their eggs in small or large clumps near the surface of water. Toads also possess poison glands behind their eyes to ward off predators.

Answer: Carnivore

A few species of frogs subsist almost entirely off of plants, and many tadpoles consume them as well. Many species of tadpoles and frogs have even been observed cannibalizing one other! Detritivores are organisms which feed off of dead organic material (plant or animal). Frogs, by contrast, typically target moving prey.

Answer: Eyes

This interesting evolutionary adaptation necessitates the retraction of the eyes towards the roof of the mouth! Frogs will often employ this mechanism several times before the food becomes completely lodged in the esophagus.

Answer: 250 million years

The earliest known species classified as a frog was "Triadobatrachus massinoti," from the early Triassic period in present-day Madagascar. The advent of multicellular organisms was approximately 1.2 billion years ago, while the earth itself is about 4.5 billion years old.

The mass extinction of the dinosaurs is thought to have occurred about 65 million years ago, though numerous species of frogs obviously survived through this period.

Answer: Amplexus

Amplexus is considered "pseudocopulation" because it does not involve direct contact between the sexual organs. The process entails the male frog mounting and grasping the body of the female with its front legs. When the female ejects her eggs, the male typically secretes a fluid containing sperm for fertilization.

Answer: 3

The amphibian heart consists of two atria and one ventricle. Mammalian hearts, by contrast, are four-chambered.

Answer: True

The lungs play just as an integral a role in frog respiration as they do in many other organisms, but did you know that frogs breathe through their skin as well? Oxygen can diffuse through a frog's epidermis and directly enter the bloodstream! When they submerge themselves completely, frogs utilize this mode of respiration exclusively to extract oxygen from the water.

As frogs lack a diaphragm to modulate the pressure in their lungs, they regulate pulmonary pressure by continuously pumping their throats.

Answer: South America

Nearly 35% of the world's frog species are indigenous to South America, and most of these are found in the Amazon region. Regrettably, frogs are disappearing globally at an alarming rate; since the 1980s, nearly 120 species have become extinct. Conservation programs worldwide are currently working to protect endangered species.

Answer: Goliath frog

This monstrous West African species can grow up to 13 inches (33 cm) and weigh nearly 8 pounds (3 kg)! Both White's tree frogs and African bull frogs (aka "Pixie" frogs) are popular pets, while the "Leopard king frog" is a creation of the author!
