Question 1

True or false: Glass Frog eggs are laid on the undersides of leaves that overhang streams.

Accepted Answer

True. Female glass frogs deposit eggs on leaves above water. When tadpoles hatch, they drop into the stream below, a common reproductive strategy in Centrolenidae.

Question 2

True or false: Glass Frogs produce a toxic poison that can harm humans on contact.

Accepted Answer

False. Glass frogs are not poisonous. They lack toxic skin secretions found in some brightly colored frogs. Their transparency serves as camouflage, not a warning signal.

Question 3

True or false: Male Glass Frogs guard the eggs laid by female Glass Frogs until the eggs hatch.

Accepted Answer

True. Male glass frogs provide parental care by guarding egg clutches from predators and keeping them moist. This behavior is well documented in many glass frog species.

Question 4

True or false: Glass Frogs are named for fragile legs that break easily like glass.

Accepted Answer

False. The name 'glass frog' refers to the transparent abdominal skin that reveals internal organs, not fragile legs. Their bones are strong and not especially breakable.

Question 5

True or false: Glass Frogs can change skin color to blend in with surroundings.

Accepted Answer

False. Glass frogs do not change color. They are typically green with translucent bellies, relying on transparency rather than color change for camouflage.

Question 6

True or false: Glass Frog skin is so transparent that the beating heart of a Glass Frog is visible from the outside.

Accepted Answer

True. Glass frogs have translucent abdominal skin that reveals internal organs. The heartbeat is clearly visible through the skin, a defining trait of the family Centrolenidae.

Question 7

True or false: Glass Frogs have green-colored bones due to a pigment called biliverdin.

Accepted Answer

True. Many glass frog species possess green bones from biliverdin, a bile pigment. This rare vertebrate trait gives bones a bright green hue visible through translucent skin.

Question 8

True or false: Glass Frogs are capable of gliding flight between trees using expanded skin flaps.

Accepted Answer

False. Glass frogs cannot glide. They are arboreal but move by jumping and climbing. Gliding is a trait of flying frogs (e.g., Rhacophorus), not glass frogs.
